So I was rear ended recently and it left me driving a rental while my car was in the shop. Perhaps needless to say I was without all of the music I had in my car. I figured it wouldn't be in the shop that long and decided to jam out on the radio. I listened to a serious amount of NPR ("Science Friday" anyone?) but I was changing stations like mad in hopes of catching a Katy Perry tune.

What is your guilty pleasure? Is it even safe to post?
