Abstract

A system and methods for acquiring cadence and selecting a song version based on the acquired cadence are disclosed. If the system detects a new cadence, then a new song version that corresponds to the new cadence can be played. The new song version playback can start in a corresponding position as the location of playback in a currently-playing song version. Each related song version shares one or more characteristics, such as melody, but is different in at least one characteristic, such as tempo.

Claims

1. A computer readable data storage device storing instructions that, when executed by at least one processing device, cause a media-playback device to:

acquire a first cadence;

initiate playback of a first song version selected from a plurality of related song versions,

wherein the selection of the first song version is based on the first cadence; and

wherein the first song version is divided into a plurality of chapters;

determine a location of playback for the first song version including a chapter number of a chapter of the plurality of chapters, and a percentage of the chapter, played;

acquire a second cadence; and

initiate playback of a second song version selected from the plurality of related song versions,

wherein the selection of the second song version is based on the second cadence;

wherein the second song version is divided into the plurality of chapters;

wherein playback of the second song version begins at a transition position in the second song version that corresponds to the location of playback for the first song version;

wherein the first song version and the second song version share at least one characteristic; and

wherein each of the plurality of related song versions is different from each of the other plurality of related song versions in at least one characteristic.

2. The computer readable data storage device of claim 1, wherein the playback of the second song version is faded in at the same time the playback of the first song version is faded out.

3. The computer readable data storage device of claim 1, wherein the first song version and the second song version share at least a melody;

and

wherein a tempo of the first song version and a tempo of the second song version are different.

4. The computer readable data storage device of claim 3, wherein a tempo of the first song version is at least about 5 beats per minute different than a tempo of the second song version.

5. The computer readable data storage device of claim 4, wherein the tempo of the first song version corresponds to the first cadence;

and

wherein the tempo of the second song version corresponds to the second cadence.

6. The computer readable data storage device of claim 3, further comprising instructions that, when executed by the at least one processing device, cause the media-playback device to:

request a stream of the first song version from a media server; and

request a stream of the second song version from the media server.

7. A method for transitioning from a first song version to a second song version, the method comprising:

acquiring a first cadence;

selecting a first song version that corresponds to the first cadence, the first song version being divided into a plurality of chapters;

streaming the first song version;

determining a location of playback for the first song version including a chapter number of a chapter of the plurality of chapters, and a percentage of the chapter, played;

acquiring a second cadence;

selecting a second song version that corresponds to the second cadence, the second song version being divided into the plurality of chapters; and

streaming the second song version beginning at a transition position in the second song version that corresponds to the location of playback for the first song version.

8. The method of claim 7, wherein each of the plurality of chapters is between about 2 minutes and about 12 minutes.

9. The method of claim 7, wherein the first song version is faded out at the same time that the second song version is faded in.

10. The method of claim 9, wherein the first song version and the second song version are faded in and faded out for about 2 seconds to about 5 seconds.

11. The method of claim 7, wherein a tempo of the first song version is at least about 5 beats per minute different from a tempo of the second song version.

12. A media server, comprising:

a database including at least one computer readable data storage device, comprising;

a plurality of song versions, wherein each of the plurality of song versions has a different tempo than each of the other song versions;

wherein the at least one computer readable data storage device having instructions stored thereon which, when executed by at least one processing device, cause the media server to;

receive a first request to begin streaming a first song version, where the first song version has a first tempo;

enable streaming of a first song version, the first song version being divided into a plurality of chapters;

receive a second request to begin streaming a second song version, wherein the second song version has a second tempo and the second song version being divided into the plurality of chapters;

wherein the second request includes a location of playback for the second song version, the location of playback including a chapter number of a chapter of the plurality of chapters, and a percentage of the chapter, played; and

wherein streaming the second song version begins at the location of playback that corresponds to the location of playback for the first song version; and

enable streaming of the second song version,

wherein the first tempo and the second tempo are different by at least about 5 beats per minute.

13. The media server of claim 12, wherein the at least one computer readable data storage device further includes instructions stored thereon which, when executed by at least one processing device, cause the media server to:

stop streaming the first song version after a predetermined time of streaming the second song version.

14. The media server of claim 12, wherein the first song version and the second song version have a same melody.
