For some reason, I cannot get Bjork's Human Behavior out of my head. I don't even know the words to the song, but that beat is just pounding away in my brain. And the last time I heard that song was at least a week ago.
My usual surefire cure to getting a song unstuck is to sing It's A Small World After All. Unfortunately, the cure is worse than the disease - you end up with It's A Small World After All stuck in your head.
