I remember reading somewhere that people who get songs stuck in their head have a psychological issue of some kind... I guess I can buy that because it happens to me ALL THE TIME!
The worst one in a long time hit me this week. I was watching VH1's "Greatest One Hit Wonders" this past weekend and I can't get "Pass the Dutchie" out of my head. Which is really sad, because I don't remember the song at all. I have only heard it on the program.
