And U2.
Re simonmoon's comment. I remember an article in TV Guide that mentioned Sherman Helmsley listening to Yes' "Close to the Edge" in his dressing room, so I believe I've connected some of the dots in your post.
Most listened to artist
If you had to guess, which 10 artists have you listened to the most in your lifetime?
Meaning every time you've selected a particular artist's 8-Track, Cassette, LP and CD at home, in your car, at a party, at the beach, wherever.
Mine, in no particular order, would be: The Beatles, Led Zeppelin, The Who, The Kinks, XTC, Elvis Costello, Kate Bush, King Crimson, David Bowie, Brand X.
