Abstract

An apparatus, program product, and method collect musical preference data from a plurality of digital media players and generate therefrom a “collaborative” playlist of media files. The collaborative playlist may be used, for example, to identify and play back media files that most, if not all, of the users of the digital media players would likely find enjoyable.

Claims

1. A method of generating a collaborative playlist of media files, the method comprising:

receiving musical preference data from each of a plurality of digital media players, wherein the musical preference data for each digital media player identifies media files resident on such digital media player; and

generating a collaborative playlist including a plurality of media files selected based upon the musical preference data received from at least a subset of the plurality of digital media players.

2. The method of claim 1, wherein generating the collaborative playlist includes including a first media file among the plurality of media files based upon the musical preference data received from at least two of the plurality of digital media players.

3. The method of claim 1, further comprising playing media files identified in the collaborative playlist in a playback device that is separate from the plurality of digital media players.

4. The method of claim 3, wherein a first media file identified in the collaborative playlist is resident on the playback device prior to receiving the musical preference data.

5. The method of claim 3, wherein a first media file identified in the collaborative playlist is resident on a first digital media player among the plurality of digital media players, the method further comprising uploading the first media file from the first audio player to the playback device.

6. The method of claim 5, wherein uploading the first media file includes uploading the entire first media file into the playback device prior to initiating playback of the first media file.

7. The method of claim 5, wherein the first media file is stored in a compressed format on the first digital media player, wherein uploading the first media file includes decompressing the first media file and transmitting the first media file to the playback device in an uncompressed format.

8. The method of claim 5, wherein the first media file is stored in a copy protected format on the first digital media player, wherein uploading the first media file includes converting the first media file to a non-copy protected format and transmitting the first media file to the playback device in the non-copy protected format.

9. The method of claim 3, further comprising updating a recently played list on a first digital media player among the plurality of digital media players to identify any media files played from the collaborative playlist by the playback device.

10. The method of claim 1, wherein the musical preference data received from a first digital media player among the plurality of digital media players includes identification data associated with at least a subset of media files stored on the first digital media player.

11. The method of claim 10, wherein the musical preference data received from the first digital media player includes identification data associated with every media file stored on the first digital media player.

12. The method of claim 10, wherein the musical preference data received from the first digital media player includes identification data associated with a plurality of media files identified in a playlist stored on the first digital media player.

13. The method of claim 10, wherein the identification data includes data selected from the group consisting of title, filename, artist, composer, performer, tempo, mood, genre, album, lyrics, comments, format, time, play count, last time played, release date, added date, and combinations thereof.

14. The method of claim 10, wherein the musical preference data received from the first digital media player includes rating data representing how well a user of the first digital media player personally likes or dislikes various media files stored on the first digital media player.

15. The method of claim 10, wherein generating the collaborative playlist includes weighting identification data associated with a subset of media files and selecting media files for inclusion in the collaborative playlist based upon the weighted identification data.

16. The method of claim 10, wherein generating the collaborative playlist includes identifying identification data that is common to multiple digital media players and selecting media files for inclusion in the collaborative playlist based upon common identification data.

17. The method of claim 1, further comprising downloading at least a portion of the collaborative playlist to a first digital media player among the plurality of digital media players.

18. The method of claim 17, wherein receiving the musical preference data includes receiving a user selection of an media file identified in the collaborative playlist from the first digital media player.

19. The method of claim 17, further comprising enabling the first digital media player to download at least one media file identified in the collaborative playlist subsequent to downloading the portion of the collaborative playlist to the first digital media player.

20. The method of claim 1, wherein the musical preference data received from a first digital media player among the plurality of digital media players includes a list of recently played media files, and wherein generating the collaborative playlist includes excluding at least one media file identified in the list of recently played media files.

21. The method of claim 1, wherein receiving the musical preference data is performed by a master device disposed proximate to and coupled wirelessly to the plurality of digital media players.

22. The method of claim 21, further comprising authenticating a first digital media player among the plurality of digital media players with the master device prior to receiving musical preference data from the first digital media player.

23. The method of claim 1, wherein the plurality of digital media players are standalone portable digital media players.

24. An apparatus, comprising:

a communications interface configured to interface with a plurality of digital media players; and

control logic coupled to the communications interface and configured to receive musical preference data from each of the plurality of digital media players and generate a collaborative playlist including a plurality of media files selected based upon the musical preference data received from at least a subset of the plurality of digital media players, wherein the musical preference data for each digital media player identifies media files resident on such digital media player.

25. The apparatus of claim 24, further comprising playback logic coupled to the control logic and configured to play back media files identified in the collaborative playlist.

26. An apparatus, comprising:

a plurality of digital media players; and

a master device in communication with the plurality of digital media players and configured to receive musical preference data from each of the plurality of digital media players and generate a collaborative playlist including a plurality of media files selected based upon the musical preference data received from at least a subset of the plurality of digital media players, wherein the musical preference data for each digital media player identifies media files resident on such digital media player.

27. A program product, comprising:

program code configured to communicate with a plurality of digital media players, receive musical preference data from each of the plurality of digital media players and generate a collaborative playlist including a plurality of media files selected based upon the musical preference data received from at least a subset of the plurality of digital media players, wherein the musical preference data for each digital media player identifies media files resident on such digital media player; and

a computer readable medium bearing the program code.
