The OST that was released (that contains 30 tracks) doesn't have a fraction of the music from the game, and there's some awesome piece of music in the game. E.g. this awesome song (http://www.youtube.com/watch?v=mUTS290zMK4&t=9m45s)

Please, someone get working on this!

Well, I did two songs myself, the XMB song and the main menu song, quality's not the best but it's a start.
