Random Music plays random mp3 tracks from your music collection. It maintains a flat database of tracks, detailed genres, and weights, and generates a weighted random playlist from the user-selected genres. The ID3 and ID3v2 fields (title/artist/album), detailed genre, and weight (0-9) for the currently-playing track can be edited, and tracks can be removed from the playlist.
For example, a user can select only tracks with a minimum weight of 5 from the subgenres "Pop - 1970s" and "R&B - 1970s", and the playlist will adjust accordingly.
