Hmm, I don't really do guilty pleasures. Music is so subjective - why feel guilty if you enjoy something? Its not like it's actively bad for you like some other guilty pleasures... Hell, I've already posted a GaGa song - so I'm not sure it is possible to go cheesier than that!
Let's go for something I always feel a little embarrassed about loving. Let's just say it isn't considered one of the artist's more important work:
