I think a site that would have a huge catalog of exclusivly non-RIAA music with a great recommedation system and streaming radio would be a real winner. I know i'd use it.
Freemusicarchive.org has a lot of good content, and the curator picks help filter some, but I agree that a recomendation system would make a site like that significantly more usable
Ideally we'd have an entire content ecosystem that was MPAA/RIAA free. Movies with cc licensed audio sold for 5-10 a pop through hulu or some other type of streaming service. This could be sent to people's set top boxes directly, bypassing the normal gatekeepers of content.
