Method and a portable electronic device for automatically rating a music track

1. A method in a portable electronic device for automatically rating a set of music tracks, the method comprising:

detecting a first user interaction during performance of a first music track comprised in the set of music tracks;

measuring a first time period between when the first music track starts playing and timing of detection of the first user interaction;

adjusting a rating of the first music track based on the detected first user interaction, thereby automatically rating the first music track,

detecting a second user interaction during performance of a second music track comprised in the set of music tracks;

measuring a second time period between when the second music track starts playing and timing of detection of the second user interaction;

adjusting a rating of the second music track based on the detected second user interaction, thereby automatically rating the second music track;

detecting a third user interaction during performance of a third music track comprised in the set of music tracks; and

adjusting a rating of the third music track based on the detected third user interaction, thereby automatically rating the third music track,

wherein the first user interaction comprises a skipping of the first music track,

wherein the second user interaction comprises a singing, by a user of the portable electronic device and which is detected by sensing sound using the portable electronic device, along with the second music track, and/or a dancing, by the user of the portable electronic device and which is detected by sensing movement of the portable electronic device,

wherein the third user interaction comprises a singing, by the user of the portable electronic device, along with a performance of the third music track by a device other than the portable electronic device, which is detected by sensing sound using the portable electronic device, and/or a dancing, by the user of the portable electronic device, along with the performance of the third music track by the device other than the portable electronic device, which is detected by sensing movement of the portable electronic device,

wherein the adjusting of the rating of the first music track comprises decreasing the rating of the first music track based on determining that the first music track is skipped at least a first plurality of times within a defined time interval, and based on determining that the first time period is shorter than a first threshold value,

wherein the adjusting the rating of the second music track comprises increasing the rating of the second music track responsive to detection of the second user interaction, responsive to a duration of the second user interaction, and responsive to determining that the second time period is longer than a second threshold value, and

wherein the adjusting the rating of the third music track comprises increasing the rating of the third music track responsive to detection of the third user interaction.

2. The method according to claim 1 , wherein the first threshold value is an absolute time period or a relative time period defined as a predefined ratio multiplied by a length of the first music track.

3. The method according to claim 1 , wherein the second threshold value is an absolute time period or a relative time period defined as a predefined ratio multiplied by a length of the second music track.

4. The method according to claim 1 , wherein said performance of the second music track comprises:

detection, by the portable electronic device, of sound relating to the second music track, wherein the sound originates from a source other than the portable electronic device.

5. The method according to claim 1 , further comprising maintaining the rating of the first music track to be constant until the first music track is skipped at least the first plurality of times within the defined time interval.

6. The method according to claim 1 , wherein the first plurality of times is greater than two times.

7. The method according to claim 1 , wherein the first plurality of times is three times.

8. The method according to claim 1 , wherein the first music track and second music track are different music tracks.

9. The method according to claim 1 , wherein the first threshold value and second threshold value are different threshold values.

10. A portable electronic device for automatically rating a music track comprised in a set of music tracks, comprising:

a processing circuit configured to detect first, second, and third user interactions during performances of first, second, and third music tracks, respectively; wherein the processing circuit is further configured to measure a first time period between when the first music track starts playing and timing of detection of the first user interaction and measure a second time period between when the second music track starts playing and timing of detection of the second user interaction; and wherein the processing circuit is further configured to adjust a rating of the first music track based on the detected first user interaction, adjust a rating of the second music track based on the detected second user interaction, and adjust a rating of the third music track based on the detected third user interaction, whereby the first, second, and third music tracks are automatically rated,

wherein the first user interaction comprises a skipping of the first music track,

wherein the second user interaction comprises dancing to and/or singing along with the second music track,

wherein the third user interaction comprises a singing along with a performance of the third music track by a device other than the portable electronic device and/or a dancing along with the performance of the third music track by the device other than the portable electronic device,

wherein the adjusting of the rating of the first music track comprises decreasing the rating of the first music track based on determining that the first music track is skipped a plurality of times within a defined time interval and based on determining that the first time period is shorter than a first threshold value,

wherein the adjusting of the rating of the second music track comprises increasing the rating of the second music track based on detecting the second user interaction, based on a duration of the second user interaction, and based on determining that the second time period is longer than a second threshold value, and

wherein the adjusting of the rating of the third music track comprises increasing the rating of the third music track based on detecting the third user interaction.

11. The portable electronic device according to claim 10 , wherein the processing circuit further is configured to maintain the rating of the music track to be constant until the music track is skipped at least the plurality of times within the defined time interval.

12. The portable electronic device according to claim 10 , wherein the plurality of times is greater than two times.

13. The portable electronic device according to claim 10 , wherein the plurality of times is three times.

14. The portable electronic device according to claim 10 , wherein the first music track and second music track are different music tracks.

15. The portable electronic device according to claim 10 , wherein the first threshold value and second threshold value are different threshold values.
