Media components can be ranked based on their influence on athletic performance. A score can be computed for a media component based on an individual's athletic performance during output of that media item in comparison with the individual's athletic performance during the output of different media items, or in the absence of any media items. The score can be used to establish an overall total score for the media component by comparing the score to one or more scores received from other individuals for the same media component. The overall total score can be used to compute a ranking for the media component by comparing the media component's overall total score with the overall total score for one or more other media components.
