OK, Frank Sinatra and Ella Fitzgerald didn't write any (many?)songs - and recorded a lot of trivial material but are they not great musicians? The real problem here is peoples inabilty to hear a great artist. Ask Bob Dylan, ask John Lennon, ask Buddy Holly, ask Gene Vincent, ask Eddie Cochran, ask Bruce Springsteen if Elvis was a great musician, and they'd all say YES. It looks like I've got some real heavyweights on my side of the debate!
