Abstract

A method for playing digital media files with a digital media player using a plurality of playlists is disclosed. One embodiment uses a plurality of playlists—instead of a single playlist—to reference a given pool of digital media files. After the songs of one playlist have been played, another playlist is selected, and songs from that playlist are played. Since the playlist selection is automatically made by the digital media player while it is offline, a fresh listening experience is created without requiring the user to connect the digital media player to the Internet. Preferably, each playlist is purposefully curated to ensure that the play order keeps the experience commensurate with a particular brand message.

Claims

1. A method for playing digital media files with a digital media player using a plurality of playlists, the method comprising:

with a digital media player comprising a memory storing a plurality of digital media files and a plurality of playlists, wherein each playlist specifies a predetermined play order of at least some of the plurality of digital media files and is created by a curator, performing the following while the digital media player is offline;

selecting a first playlist from the plurality of playlists;

playing the digital media files specified in the first playlist; and

after playing the digital media files specified in the first playlist, selecting a second playlist from the plurality of playlists.

2. The method of claim 1, wherein the second playlist is a next playlist after the first playlist in the plurality of playlists.

3. The method of claim 1, wherein the second playlist is selected in a random fashion from the plurality of playlists.

4. The method of claim 1, wherein the second playlist is selected in a pseudo-random fashion from the plurality of playlists.

5. The method of claim 1, wherein at least one playlist in the plurality of playlists specifies at least one digital media file that is not specified by another playlist in the plurality of playlists.

6. The method of claim 1, wherein at least two playlists in the plurality of playlists specify the same digital media files but sequence those digital media files in a different predetermined play order.

7. The method of claim 1, wherein the plurality of playlists are associated with a first channel, wherein the memory further stores a second plurality of playlists associated with a second channel, and wherein the method further comprises receiving a user-selection of one of the first and second channels.

8. The method of claim 7, wherein the first channel and the second channel share at least one of the plurality of digital media files.

9. The method of claim 7, wherein the memory further stores at least one additional digital media file that is unique to the second channel and is not specified in any of the playlists associated with the first channel.

10. The method of claim 7, wherein the user-selection of the one of the first and second channels is received by receiving a user-selection of a user input element of the digital media player.

11. The method of claim 10, wherein the user input element comprises at least one of a next channel user input element and a previous channel user input element.

12. The method of claim 1, wherein the memory comprises a solid-state memory in a memory card that is removably connectable with the digital media player.

13. The method of claim 1, wherein the memory comprises a solid-state memory embedded in the digital media player.

14. The method of claim 1, wherein the digital media files comprise digital audio files.

15. A method for playing digital media files with a digital media player, the method comprising:

with a digital media player comprising a memory storing a plurality of digital media files and a plurality of playlists, wherein each playlist specifies a predetermined play order of at least some of the plurality of digital media files, and wherein at least one playlist in the plurality of playlists specifies at least one digital media file that is not specified by another playlist in the plurality of playlists, performing the following while the digital media player is offline;

selecting a first playlist from the plurality of playlists;

playing the digital media files specified in the first playlist; and

after playing the digital media files specified in the first playlist, selecting a second playlist from the plurality of playlists.

16. The method of claim 15, wherein each playlist is created by a curator.

17. The method of claim 15, wherein the second playlist is a next playlist after the first playlist in the plurality of playlists.

18. The method of claim 15, wherein the second playlist is selected in a random fashion from the plurality of playlists.

19. The method of claim 15, wherein the second playlist is selected in a pseudo-random fashion from the plurality of playlists.

20. A method for playing digital media files with a digital media player, the method comprising:

with a digital media player comprising a memory storing a plurality of digital media files, a first plurality of playlists associated with a first channel, and a second plurality of playlists associated with a second channel, wherein each playlist specifies a predetermined play order of at least some of the plurality of digital media files, performing the following while the digital media player is offline;

receiving a user-selection of one of the first and second channels;

selecting a first playlist from the plurality of playlists associated with the selected channel;

playing the digital media files specified in the first playlist; and

after playing the digital media files specified in the first playlist, selecting a second playlist from the plurality of playlists associated with the selected channel.

21. The method of claim 20, wherein each playlist is created by a curator.

22. The method of claim 20, wherein the second playlist is a next playlist after the first playlist in the plurality of playlists associated with the selected channel.

23. The method of claim 20, wherein the second playlist is selected in a random fashion from the plurality of playlists associated with the selected channel.

24. The method of claim 20, wherein the second playlist is selected in a pseudo-random fashion from the plurality of playlists associated with the selected channel.

25. The method of claim 20, wherein at least one playlist in the plurality of playlists associated with the selected channel specifies at least one digital media file that is not specified by another playlist in the plurality of playlists associated with the selected channel.

26. The method of claim 20, wherein at least two playlists in the plurality of playlists associated with the selected channel specify the same digital media files but sequence those digital media files in a different predetermined play order.

27. The method of claim 20, wherein the first channel and the second channel share at least one of the plurality of digital media files.

28. The method of claim 20, wherein the memory further stores at least one additional digital media file that is unique to the second channel and is not specified in any of the playlists associated with the first channel.

29. The method of claim 20, wherein the user-selection of the one of the first and second channels is received by receiving a user-selection of a user input element of the digital media player.

30. The method of claim 29, wherein the user input element comprises at least one of a next channel user input element and a previous channel user input element.
