Musical Collaboration by Opt-in and Mass Beat Channels

There could be channels for each beat/tempo, and an unlimited number of contibutors could participate in the creation of music within each channel. Any listener could select the combination of contributors and listen to the mixed track. Popular and preset groups could simplify selection, and descriptive fields for contributors could help improve custom selections. Contributor-defined sub-channels could branch off from the public ones. This system would allow unlimited musical collaboration in a way that provides compatibility and flexibility on a global scale.
