Guilty musical pleasures?

[Rev. Rye]

How do the Traveling Wilburys count as a Guilty Pleasure? It's a supergroup starring four rock n roll legends from different decades: Roy Orbison, Bob Dylan, George Harrison, and Tom Petty, and the ELO frontman who could bring them together. I doubt that you'd consider any of the four to be a guilty pleasure, so why consider them together a "guilty pleasure?" Granted, Vol. 3 might not be as good as the first album, but still.
