I kind of don't believe in guilty pleasures. I think this is similar to the concept of liking something "ironically." As I've said many times, you either like it or you don't. I wear my musical tastes on my sleeve. I'll openly admit to liking what I like, and am not embarrassed by anything in my record collection. Not the Partridge Family, not Poison, not Hall and Oates, not George Michael, not the Carpenters, etc. etc. etc.
Ergo, I abstain from participating today.
