I can't agree more. Social music is the future of music, but it's struggling.

The variety of online music sites/services is a strange double edged sword - I'm really happy that so many diverse music products exist, but the fragmentation of online music makes it nearly impossible to build a meaningful social experience around music. An Rdio user interacts with and consumes music one way, a SoundCloud user thinks of online music another way, and the two of them can't even figure out if they're listening to the same song - literally.

Accurate, cross-platform music ID resolution is the first step in fixing all of this. And it's not an easy problem.

(Full disclosure: I build http://flock.fm which uses EchoNest for song/artist resolution, and I also recently won some swag from them in a contest.)
