You forgot The Beatles! How dare they use the names of the band members in their lyrics?!
I considered them but left em out. Also considered bands with short one-word names that I'm sure they've uttered in lyrics (like Yes and Live, and arguably The Who), and bands that have made quasi-reference to their names, like Pink Floyd (Have A Cigar), King Crimson (The Court of the Crimson King), Queensryche (Queen of the Reich), etcetc.
