PROBLEM TO BE SOLVED: To provide techniques for generating and using performance metadata (P metadata) associated with a media piece such as music or video.SOLUTION: An electronic device can monitor a user's workout performance while playing a particular media piece. Workout performance includes the user's rate of motion and/or physiological metrics of the user. Based on the user's workout performance, the electronic device can create new or modify existing P metadata associated with the media piece. The P metadata based on a particular user's workout performance in response to a media piece may be combined with collective P metadata based on the workout performance of multiple users in response to the media piece. The combined P metadata may then be stored as new collective metadata. Accordingly, the collective P metadata can represent the average response to the media piece over the multiple users. |
