Abstract: Described herein is a system for automatically mixing music. An ordering component receives information regarding a set of songs, obtains pre-analyzed metadata about songs in the set of songs, and, based upon the pre-analyzed metadata orders the songs into a mix based upon an analysis of beats-per-minute and song key. A cue point component, based upon a user preference, selects one or more cue points from the pre-analyzed metadata for transitions into and/or out of the songs in the mix. A transition component, based upon the user preference and information derived from the pre-analyzed metadata for each section of a particular song, configures transitions between songs in the mix. The system can store metadata about the mix for playback.
