Abstract

An embodiment may involve a server device transmitting, over a wide area network, a first playlist with a first duration to a client device. Possibly while the client device is playing out a current audio file of a first plurality of audio files in the playlist, the server device may receive an instruction from the client device and generate a second playlist. The second playlist may include references to a second plurality of audio files, where playout of the second plurality of audio files may have a duration that is less than the duration of the playout of the first plurality of audio files. The server device may transmit, over the wide area network, the second playlist to the client device. Reception of the second playlist at the client device may cause the audio player application to retrieve and play out the second plurality of audio files.

First claim

What is claimed is:

1. A method comprising:
generating, by a server device, a first playlist that has a first duration;
transmitting, by the server device, the first playlist to a client device, wherein reception of the first playlist at the client device causes the client device to retrieve and play out at least some of a first plurality of media files referenced by the first playlist;
receiving, by the server device, a target duration from the client device;
in response to receiving the target duration, generating, by the server device, a second playlist, wherein the second playlist has a second duration that is less than the first duration and is based on the target duration; and
transmitting, by the server device, the second playlist to the client device, wherein reception of the second playlist at the client device causes the client device to, after playout of a current media file of the first plurality of media files completes: (i) stop playing out the first plurality of media files, and (ii) retrieve and play out at least some of a second plurality of media files referenced by the second playlist.

2. The method of claim 1 , wherein the second duration is also within a threshold duration of the target duration.

3. The method of claim 1 , wherein the second duration is based on the target duration minus any time remaining for playout of the current media file.

4. The method of claim 1 , wherein the second plurality of media files does not include any of the media files of the first plurality of media files that are before the current media file in an ordering of the first plurality of media files.

5. The method of claim 1 , wherein the second plurality of media files includes at least some audio files of the first plurality of media files that are after the current media file in an ordering of the first plurality of media files.

6. The method of claim 1 , wherein media files in the first plurality of media files are each associated with a higher priority or a lower priority, and wherein the second plurality of media files includes media files from the first plurality of media files associated with the higher priority.

7. A method comprising:
generating, by a server device, a first playlist that has a first duration;
transmitting, by the server device, the first playlist to a client device, wherein reception of the first playlist at the client device causes the client device to retrieve and play out at least some of a first plurality of media files referenced by the first playlist;
receiving, by the server device, a target duration from the client device;
in response to receiving the target duration, generating, by the server device, a second playlist, wherein the second playlist has a second duration that is within a threshold duration of the target duration; and
transmitting, by the server device, the second playlist to the client device, wherein reception of the second playlist at the client device causes the client device to, after playout of a current media file of the first plurality of media files completes: (i) stop playing out the first plurality of media files, and (ii) retrieve and play out at least some of a second plurality of media files referenced by the second playlist.

8. The method of claim 7 , wherein the second duration is less than the first duration.

9. The method of claim 7 , wherein the second duration is based on the target duration minus any time remaining for playout of the current media file.

10. The method of claim 7 , wherein the second plurality of media files does not include any of the media files of the first plurality of media files that are before the current media file in an ordering of the first plurality of media files.

11. The method of claim 7 , wherein the second plurality of media files includes at least some media files of the first plurality of media files that are after the current media file in an ordering of the first plurality of media files.

12. An article of manufacture including a non-transitory computer-readable medium, having stored thereon program instructions that, upon execution by a server device, cause the server device to perform operations comprising:
generating a first playlist that has a first duration;
transmitting the first playlist to a client device, wherein reception of the first playlist at the client device causes the client device to retrieve and play out at least some of a first plurality of media files referenced by the first playlist;
receiving a target duration from the client device;
in response to receiving the target duration, generating a second playlist, wherein the second playlist has a second duration that is less than the first duration and is based on the target duration; and
transmitting the second playlist to the client device, wherein reception of the second playlist at the client device causes the client device to, after playout of a current media file of the first plurality of media files completes: (i) stop playing out the first plurality of media files, and (ii) retrieve and play out at least some of a second plurality of media files referenced by the second playlist.

13. The method of claim 1 , wherein the target duration is provided by a user of the client device.

14. The method of claim 1 , wherein generating the first playlist or the second playlist comprises selecting media files with associated mood descriptors that do not have conflicting moods.

15. The method of claim 14 , wherein selecting media files with associated mood descriptors comprises selecting the media files so that the associated mood descriptors follow a pre-defined theme for the first playlist or the second playlist.

16. The method of claim 1 , wherein the client device terminates playout of the first playlist or the second playlist when a user-defined timer has elapsed.

17. The method of claim 7 , wherein the target duration is provided by a user of the client device.

18. The method of claim 7 , wherein generating the first playlist or the second playlist comprises selecting media files with associated mood descriptors that do not have conflicting moods.

19. The method of claim 18 , wherein selecting media files with associated mood descriptors comprises selecting the media files so that the associated mood descriptors follow a pre-defined theme for the first playlist or the second playlist.

20. The method of claim 7 , wherein the client device terminates playout of the first playlist or the second playlist when a user-defined timer has elapsed.
