Musical Guilty Pleasures?

I don't want to hear any "I'm not ashamed of anything I listen to" responses. That's a boring response. I'm not asking if you feel guilty for listening to a particular band.

Everybody has their own musical preferences. And while many try to pull the "I like all music" thing, nobody is 100% un-biased in terms of their musical tastes. Regardless of how open-minded you think you are in regards to music, there are certain styles of music that you prefer over others, and you know it. There's nothing wrong with that. It's human nature.

With that in mind, what artists do you listen to that contradict your normal preferences? What bands do you have in your playlist, or what CDs do you have in your collection that seem extremely out of place next to the rest of your music?

I'll get this started with my own guilty pleasures.

Billy Joel - Innocent Man and River of Dreams in particular.
Jimmy Buffett - Everything he's ever done. Jimmy is the man.
Bruce Springsteen - Again, pretty much everything.
Prozzak - I only own Hot Show because Saturday People is impossible to find.
Nickelback - I hate these guys, but there are a couple of good songs off their first album.
The Wallflowers - I can't stand that "One Headlight" song, but the rest of their stuff is actually pretty good.
They Might be Giants - Pretty much everything they've ever done.

That's all I can think of off the top of my head. If I remember more, I'll post them.
