Is that the best anyone can do? I guess I shouldn't be surprised, it's a pretty diverse group and fairly accepting (well, not of Opeth board members or new Metallica, but other than that...)
OK, well here's my not so secret "guilty pleasures", and I'm not ashamed:
Erasure.
New Order
Divine
Weird Al (Yeah, I know, but I like ALL his parodies, including the Rap and the Country)
Yaz
Grandmaster Flash (esp. "White Lines (Don't Do It)"
...and other silly, trite 80's music. Frankly, there's really too much to name.
