So, Patrick Bateman has Huey Lewis & Genesis and if I remember rightly, though it has been ten years since I read it, the character in Ecstasy is hung up on ABC.

Are there any other fictional weirdos with obsessions with a certain artist or album?

And what would be the artist of choice if you were writing about a blood hungry lunatic?

I want to say Tom Waits but I'm going to plump for Roxy Music instead. Or maybe Kid Creole & the Coconuts.
