Patent Application
20140067827
Aspects of the present application relate generally to the field of processing digital media content. More specifically, certain implementations of the present disclosure relate to system and/or method for automatically generating music playlists based on an implicitly selected seed.
Users frequently want to quickly start playing an enjoyable mix of music with a minimum of effort spent selecting what to play. There are existing solutions for automatically creating a playlist based on a user selected seed song, from which similar songs are chosen by a music-management system in order to populate the playlist. For example, manually-seeded music services, such as Pandora and iTunes Genius, require the user to select a seed song so that a playlist can be created. However, with the continuously growing personal music libraries, the manual selection of seed songs still requires a fair amount of user effort and time to navigate through their music collection and select an appropriate seed song.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such approaches with some aspects of the present method and apparatus set forth in the remainder of this disclosure with reference to the drawings.

A first playlist with a plurality of songs from the music library may be generated. The plurality of songs in the first playlist may be automatically selected to be similar to the selected one of the plurality of seed songs.
The at least one selection criteria may include one or more of a highest song rating, frequency of song playback within a determined time period, recent song purchase, and social media posting by a user regarding a song from the music library. The one or more circuits may be operable to generate a second playlist from the music library based on another selected (e.g., randomly) one of the plurality of seed songs. The first and second playlists may be communicated to a user device for display. The one or more circuits may be operable to generate a combined music art icon of the first playlist for display at a user device. The combined music art icon may include music art for each of the plurality of songs in the first playlist.
The one or more circuits may be operable to cause display of the combined music art icon at the user device. The display may include an indication of the at least one selection criteria and the selected one of the plurality of seed songs. The one or more circuits may be operable to assign a score to each song in the music library based on whether the song satisfies the at least one selection criteria. The one or more circuits may be operable to select the plurality of seed songs by selecting a determined number of songs from the music library based on a maximum assigned score. The one or more circuits may be operable to send a user notification of the generated first playlist to a user device, and in response to an input from the user, save the first playlist in memory for subsequent use. The one or more circuits may be operable to generate a new playlist with a plurality of songs from the music library. The plurality of songs in the new playlist may be automatically selected to be similar to a new selected one of the plurality of seed songs (e.g., randomly selected), and the generating of the new playlist may take place upon restarting of the user device.
In accordance with yet another embodiment of the disclosure, a method for generating a playlist may include selecting (e.g., randomly) a plurality of selection criteria associated with song popularity. At least one of the plurality of selection criteria may be based on a user interaction on a social web site regarding at least one of a plurality of songs in a music library. A score may be assigned to each of the plurality of songs in the music library based on the at least one selection criteria. The plurality of songs in the music library may be ranked according to the assigned score. A determined number of top ranked songs may be selected from the ranked plurality of songs as a plurality of seed songs. At least one playlist with a plurality of songs from the music library may be generated. The plurality of songs in the at least one playlist may be automatically selected to be similar to a selected (e.g., randomly) at least one of the plurality of seed songs. The plurality of songs in the at least one playlist may also be automatically selected to be similar to a randomly selected at least two of the plurality of the seed songs.

The communication network 106 may comprise the Internet as well as any combination of wired and/or wireless networks, such as a Wi-Fi network, a WiMAX network (or another 802.1x enabled network), a satellite network, or a cellular telephone network.
The media backend 106 may comprise suitable circuitry, logic and/or code and may be operable to provide digital media related services to the client device 102. For example, the media backend 106 may provide digital media storage and management services, subscription services (e.g., streaming media subscription services), and digital media provisioning services (e.g., automatically generating playlists from a digital media library, as well as sale, transcoding and download of digital media). The media backend 106 may also comprise memory/storage 114, a communication subsystem 116, an automatic playlist generation module (APGM) 115, and a central processing unit (CPU) 118. Additionally, the media backend 106 may operate as, for example, a streaming content provider and may be operable to keep track of each digital media item that a user (e.g., user A) has viewed or listened to. In this regard, the media backend may store a play or view count of digital media items in the memory/storage block 114, as well as metadata information associated with digital media items from the digital media library 108 (e.g., rating, frequency of play, date of purchase/download or other metadata indicating user affinity to a specific digital media item).
Even though the media backend 106 is illustrated as being separate from the user device 102, the disclosure may not be limited in this regard. More specifically, the media backend 106 may be implemented as part of the user device 102 or another computing device of user A.
The communication subsystem 116 may comprise suitable circuitry, logic, and/or code and may be operable to provide communication of information to and from the digital media library 108, the social network 104, and/or the client device 102. For example, the communication subsystem 116 may include one or more transceivers for providing wired and/or wireless communication of data to and from the digital media library 108 (via the wired and/or wireless communication link 124d), and/or the client device 102 or the social network 104 via the communication network 106 and the communication links 1124c, 124a, and 124b.
The automatic playlist generation module (APGM) 115 may comprise suitable circuitry, logic and/or code and may be operable to automatically generate one or more playlists of digital media items selected from the digital media library 108. More specifically, the APGM 115 may be operable to automatically select a seed (e.g., a seed song) based on user behavior indicating affinity to certain digital media, and then generate one or more playlists based on the seed. The playlists may be communicated to the user device 102 for display on the screen 103 and consumption of the corresponding digital media in the playlist by user A.
The digital media library 108 may comprise suitable circuitry, logic and/or code and may be operable to manage a plurality of digital media items (DMIs) 120, . . . , 122. The plurality of DMIs 120, . . . , 122 may comprise a plurality of songs forming a personal music library of user A. Even though the digital media library 108 is illustrated as being separate from the media backend 106, the disclosure may not be limited in this regard. More specifically, the digital media library 108 may be implemented as part of the media backend 106 or the user device 102.
The social network 104 may comprise suitable circuitry, logic and/or code and may be used by the media backend 106 during the automatic generation of the playlists of digital media items by the APGM 115. More specifically, the social network 104 may comprise a profile 112 and online posts/shares 113 of user A. The APGM 115 may communicate with the social network 104 (via communication links 124c, 124b and communication network 110), and obtain digital media related information from the profile 112 and/or the posts/shares 113. Such information may indicate affinity of user A to certain digital media item(s) from the plurality of DMIs 120, . . . , 122 stored in the digital media library 108. For example, the APGM 115 may obtain information related to user A's posts or shares or profile-specific preferences related to a digital media genre (e.g., a specific type of music user A likes) or a specific digital media item user A likes (e.g., a recently heard or purchased song). This digital media related information may then be used by the APGM 115 for the automatic selection of a seed digital media item (e.g., one or more seed songs) and generating the playlist for user A.
In operation, user A may use the client device 102 to subscribe to a digital media provisioning and management service provided by the media backend 106. As part of the digital media provisioning and management service, user A may purchase, download, store, organize and generally have access to a plurality of digital media items 120, . . . , 122 stored in the digital media library 108. For example, user A may have access to digital media items 120, . . . , 122, which may comprise one or more streaming videos, songs or other types of digital media items. Additionally, user A may have previously purchased (or downloaded) the digital media items 120, . . . , 122, and may download (and store) any of the digital media items 120, . . . , 122 locally at the client device 102, or at a cloud-based digital media locker service.
Additionally, as part of the digital media related services provided by the media backend 106, the APGM 115 may automatically generate a list with a plurality of digital media seeds (e.g., seed songs) based on user A's affinity for certain digital media items within the digital media library 108. The APGM 115 may then generate one or more playlists based on at least one digital media seed selected (e.g., randomly) from the generated plurality of digital media seeds. The generated playlists may be communicated to the user device 102 and may be automatically displayed on the screen 102 as soon as the user device 102 is turned ON or user A accesses digital media management functionalities provided by the media backend 106 (e.g., user A accesses a music or other digital media online store or digital media collection management functionalities related to user A's digital media collection of items 120, . . . , 122).
The APGM 115 may comprise a seed filter 202, a selector module 204, and a similarity engine 206, which may be used during the automatic generation of playlists. More specifically, the seed filter 202 may comprise suitable circuitry, logic and/or code and may be operable to use implicit information from a user's digital media library to generate one or more seed list. More specifically, the seed filter 202 may use one or more selection criteria associated with digital media (e.g., song) popularity, as well as user behavior that indicates affinity to specific digital media, for selecting a seed list from the digital media library 108. For example, the seed filter 202 may use the following selection criteria associated with user affinity to a song during the seed list selection:
Song rating (e.g., the user gave the song a high rating, such as recent “thumbs up” or 4-5 stars);
High play count (e.g., the user has played the song more than X times in a given time period);
Recently purchased (e.g., the user has recently purchased a song);
“Old favorite” song (e.g., the user has listened to the song more than X times in the past, but has not heard the song in the last certain number of days/weeks/months);
Social network popularity (e.g., the user's friends with similar music tastes have listened to the song more than X times in a given time period); and
Genre Popularity (e.g., the user owns or listens to a lot of music from a specific genre).
In accordance with an embodiment of the disclosure, the seed filter 202 may use the above criteria as well as other selection criteria associated with user affinity to a song in order to select a seed list from the digital media library 108. Based on the selection criteria selected, the seed filter 202 may assign weights (or scores) for each song in the user A's digital media library of DMIs 120, . . . , 122. The seed filter 202 may use one or more of the selection criteria at any given time, where the one or more selection criteria may be selected (e.g., randomly) by the CPU 118, or may be pre-selected by user A.
For example, if “song rating” and “social network popularity” are selected as filtering criteria, the seed filter 202 may obtain metadata information associated with song rating for each of DMIs 120, . . . , 122. If the song rating for a song is above a certain threshold, then the song may be assigned certain weight (or score). The seed filter 202 may then obtain “social network popularity” information based on profile information 112 and/or posts/shares information 113 associated with user A on the social network 104. For example, user A may have a post that he enjoys classical music. The seed filter 202 may then assign an additional weight (or score) to all classical music tracks within the DMIs 120, . . . , 122. The seed filter 202 may then rank the DMIs 120, . . . , 122 according to total score and may select a determined number of the top scoring DMIs (e.g., songs with the highest weight or score given) as the seed list.
The selector module 204 may comprise suitable circuitry, logic and/or code and may be operable to perform a selection of one or more seed songs from the seed list generated by the seed filter 202. For example, the selector module 204 may be operable to perform a random selection of one or more seed songs from the seed list generated by the seed filter 202.
The similarity engine 206 may comprise suitable circuitry, logic and/or code and may be operable to generate a playlist based on a seed song or metadata from the seed song. More specifically, after receiving a seed song (or metadata from the seed song), the similarity engine 206 may generate a playlist with a determined number of songs selected from, for example, the DMIs 120, . . . , 122 in the digital media library 108. The determined number of songs may be selected based on similarity to the received seed song. Various techniques may be used in selecting songs similar to the seed song, such as acoustic similarity, genre similarity, artist similarity, as well as other techniques.
Even though the seed filter 202, the selector module 204 and the similarity engine 206 are illustrated as implemented within the media backend 106, the present disclosure may not be limited in this regard. More specifically, the seed filter 202, the selector module 204 and the similarity engine 206 may be implemented as separate functional modules or as part of other network devices.
In operation, the seed filter 202 in the media back end 106 may find seed tracks based on implicit information from user A's digital media library (e.g., DMIs 120, . . . , 122). More specifically, the seed filter 202 may select (e.g., randomly) one or more of the selection criteria described above (or other similar criteria) and apply the selection criteria to the DMIs 120, . . . , 122 in the digital media library 108. After applying the selection criteria, a seed list 208 may be generated with seed songs 210, . . . , 212 that have the highest weight (or score) after applying the selection criteria. The selector module 204 may randomly select one or more of the seed songs (e.g., 210, . . . , 214), which may be used by the similarity engine to generate corresponding playlists 224, . . . , 226 based on selected seeds 210, . . . , 214.
The playlists 224, . . . , 226 may be generated as a background process to the user device 102, based on metadata, play/purchase history, social signals (e.g., from the social network 104) or other implicit information from a user's digital media library to generate one or more seeds, and at least one playlist from the one or more seeds.
For example, the seed filter 202 may use the “recently purchased song” selection criteria (or filter). The seed filter 202 may then search the DMIs 120, . . . , 122 for the most recently purchased song. The most recently purchased song will be selected as the seed song (e.g., seed 210). Metadata associated with the seed song 210 may then be communicated to the similarity engine 206 to generate a playlist (e.g., playlist 224), which may include the seed song (seed 210) and additional songs (216, . . . , 218) which are similar to the seed. The one or more generated playlists (e.g., 224, . . . , 226) may be communicated to the user device 102 and displayed to user A the next time the user device 102 is turned ON and user A logs into digital media storage/management services platform of the media backend 106.
In accordance with an example embodiment of the disclosure, more than one selection criteria may be used, and each playlists may combine songs that are similar to a plurality of selected seeds, instead of just one seed. For example, the seed filter 202 may use the “recently purchased song” and the “total play count” (or “high play count”) selection criteria (or filters). The seed filter 202 may then search the DMIs 120, . . . , 122 for the most recently purchased songs (e.g., the top 100 most recently purchased songs). The seed filter 202 may then search the top 100 most recently purchased songs for the songs with the highest play count and most recently purchased songs (e.g., the top 50 highest play count songs). The highest play count song (after “recently purchased song” filter has been applied) may be selected as the seed song (e.g., seed 210). Metadata or social network related information (e.g., 112, 113) associated with the seed song 210 may then be communicated to the similarity engine 206 to generate a playlist (e.g., playlist 224), which may include the seed song (seed 210) and additional songs (216, . . . , 218) which are similar to the seed 210. The one or more generated playlists (e.g., 224, . . . , 226) may be communicated to the user device 102 and displayed to user A the next time the user device 102 is turned ON and user A logs into digital media storage/management services platform of the media backend 106.
In accordance with another example embodiment of the disclosure, each of the playlists 224, . . . , 226 may include songs from the corresponding seed for that playlist as well as songs from another seed from the seed list 208. For example, playlist 224 may include the seed song (seed 210) and additional songs (216, . . . , 218) which are similar to the seed 210. However, playlist 224 may also include additional songs (e.g., one or more of DMIs 220, . . . , 222), which are similar to another seed (e.g., seed 214) from the seed list 208.
As seen in
Additionally, user A may have an option to delete one or more of the auto-generated playlists 306, . . . , 314 or generate one or more additional playlist automatically (after one is deleted) or upon demand. In either of these cases, a request for a new playlist may be communicated to the media backend 106 to generate a new automatic playlist, as described above in reference to
Other implementations may provide a non-transitory computer readable medium and/or storage medium, and/or a non-transitory machine readable medium and/or storage medium, having stored thereon, a machine code and/or a computer program having at least one code section executable by a machine and/or a computer, thereby causing the machine and/or computer to perform the steps as described herein for generating a playlist.
