Abstract

In some specific implementations, tracks of music make up a body of tracks available for playing. Metadata about the track may indicate relationships among the tracks, for example that they are jazz. Information about explicit and implicit reactions of a user to the playing of one or more of the tracks is stored. All of the available tracks are scored either directly as a result of the user reaction information or based on the relationships of the tracks to one another. The scoring is updated every time a user provides explicit or implicit reaction to a played track. Tracks are selected automatically for play based on the ratings or scores at the time of the selection and on a probabilistic technique that assures that every track has some possibility of being played at any time.
