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.

Claims

1. A method comprising:

generating, by a server device, a first playlist for a client device, wherein the first playlist includes references to a first plurality of audio files in a first specified order, wherein playout of the first plurality of audio files has a first duration, wherein the client device and the server device are in communication with one another by way of a wide-area network, and wherein the client device includes an audio player application;

transmitting, by the server device over the wide area network, the first playlist to the client device, wherein reception of the first playlist at the client device causes the audio player application to retrieve and play out at least some of the first plurality of audio files in the first specified order;

while the client device is playing out a current audio file of the first plurality of audio files, receiving, by the server device, an instruction from the client device, wherein the instruction specifies that the client device has activated a sleep timer with a target duration;

in response to receiving the instruction, generating, by the server device, a second playlist, wherein the second playlist includes references to a second plurality of audio files in a second specified order, wherein playout of the second plurality of audio files has a second duration that is;

less than the first duration and within a threshold duration of the target duration; and

transmitting, by the server device over the wide area network, the second playlist to the client device, wherein reception of the second playlist at the client device causes the audio player application to, after playout of the current audio file completes, stop playing out audio files from the first plurality of audio files and retrieve and play out the second plurality of audio files in the second specified order.

2. The method of claim 1, wherein the second plurality of audio files does not include any audio files of the first plurality of audio files that are before the current audio file in the first specified order.

3. The method of claim 1, wherein the second plurality of audio files includes at least some audio files of the first plurality of audio files that are after the current audio file in the first specified order.

4. The method of claim 3, wherein the audio files in the first plurality of audio files are associated with respective priorities, and wherein generating the second playlist comprises selecting the second plurality of audio files from the audio files of the first plurality of audio files while giving preference to higher priority audio files over lower priority audio files.

5. The method of claim 4, wherein audio files containing advertisements are associated with higher priorities than audio files containing music.

6. The method of claim 3, wherein generating the second playlist comprises selecting, from the audio files in the first plurality of audio files that are after the current audio file in the first specified order, the second plurality of audio files.

7. The method of claim 1, wherein the threshold duration is three minutes or less.

8. The method of claim 1, wherein, due to activation of the sleep timer, the second plurality of audio files is selected based on preferences for (i) slow tempos, (ii) narrow dynamic ranges, or (iii) lower volumes.

17. The method of claim 1, wherein the second duration is based on a remaining playout time of the current audio file subtracted from a remaining playout time of the first playlist.

9. 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 for a client device, wherein the first playlist includes references to a first plurality of audio files in a first specified order, wherein playout of the first plurality of audio files has a first duration, wherein the client device and the server device are in communication with one another by way of a wide-area network, and wherein the client device includes an audio player application;

transmitting, over the wide area network, the first playlist to the client device, wherein reception of the first playlist at the client device causes the audio player application to retrieve and play out at least some of the first plurality of audio files in the first specified order;

while the client device is playing out a current audio file of the first plurality of audio files, receiving an instruction from the client device, wherein the instruction specifies that the client device has activated a sleep timer with a target duration;

in response to receiving the instruction, generating a second playlist, wherein the second playlist includes references to a second plurality of audio files in a second specified order, wherein playout of the second plurality of audio files has a second duration that is;

less than the first duration and within a threshold duration of the target duration; and

transmitting, over the wide area network, the second playlist to the client device, wherein reception of the second playlist at the client device causes the audio player application to, after playout of the current audio file completes, stop playing out audio files from the first plurality of audio files and retrieve and play out the second plurality of audio files in the second specified order.

10. The article of manufacture of claim 9, wherein the second plurality of audio files does not include any audio files of the first plurality of audio files that are before the current audio file in the first specified order.

11. The article of manufacture of claim 9, wherein the second plurality of audio files includes at least some audio files of the first plurality of audio files that are after the current audio file in the first specified order.

12. The article of manufacture of claim 11, wherein the audio files in the first plurality of audio files are associated with respective priorities, and wherein generating the second playlist comprises selecting the second plurality of audio files from the audio files of the first plurality of audio files while giving preference to higher priority audio files over lower priority audio files.

13. The article of manufacture of claim 12, wherein audio files containing advertisements are associated with higher priorities than audio files containing music.

14. The article of manufacture of claim 11, wherein generating the second playlist comprises selecting, from the audio files in the first plurality of audio files that are after the current audio file in the first specified order, the second plurality of audio files.

15. The article of manufacture of claim 9, wherein the threshold duration is three minutes or less.

16. The article of manufacture of claim 9, wherein, due to activation of the sleep timer, the second plurality of audio files is selected based on preferences for (i) slow tempos, (ii) narrow dynamic ranges, or (iii) lower volumes.

18. The article of manufacture of claim 9, wherein the second duration is based on a remaining playout time of the current audio file subtracted from a remaining playout time of the first playlist.
