What was the last song you couldn't get out of your head no matter how hard you tried?
Everything Burns will not flipping leave my head, now that I've favorited a vid that uses the song:

Also... and God, this is embarrassing, but the He-Man and She-Ra themes also get stuck in my head. I don't know why, since I never even watched She-Ra (No, I swear! Okay, maybe I watched a few episodes of it before I decided it was treacly.)
In fact, you know what? I always seem to have some song or another running through my brain, non-stop. So, I guess that it is actually a small blessing that it does manage to hit the CD changer once in a while.
