I don't remember anyone calling it innovation. How about a nice feature addition to a service? After all, Spotify also has many other "innovations" Grooveshark doesn't: a clear legality, accurate track and artist catalogues, and paying all of their artists (even if it isn't much, it is certainly more than Grooveshark).
