I've just been trying to work out what my earworm is, turns out it's Metallica and Carpe Diem Baby. Mike's been playing Reload on and off quite a bit lately I think.
You think you've got problems? For the last couple of days I've had the Muppets theme as an earworm. Except that I've had "It's time to worship Satan" instead of "It's time to put on make-up".
