30 day song challenge: Day 2

My least favorite song? I don't usually go listening to music I don't like, so I don't really know what it is.

I heard a stupid song in Kmart the other day ... I think it's called Dirty Little Secret. I don't usually like rap, although there are exceptions ... And I really don't like Carrie Underwood or Justin Bieber much at all.

Does anyone have a least favorite song? Who goes around picking songs they hate?
