I wasn't familiar with Grooveshark, and I'm having trouble figuring out their licensing arrangement. For example, they have quite a few tunes by Pink Floyd, who have instructed EMI to keep their music off of iTunes, Spotify, and all other sites which would allow "per-song" downloading or streaming-- they want to keep the integrity of the albums intact. This, coupled with the bits of the Grooveshark FAQ like "All of the music on Grooveshark is uploaded by the users!" makes me think that Grooveshark is not long for this world, once the RIAA discovers them.
