Ever heard a song like that? A song you can't stop listening to? And everywhere you go you can hear it playing over and over in your mind, even when you're trying to listen to other music?
To be honest, I can't imagine this thread succeeding too well because no one will want to get an ear worm, so that's why I'm not sharing any, because if I think of one, it's stuck in my head, and I do not want that.

For months, whenever I went to work, all I could hear in my mind was "Every Me Every You" by Placebo*. I'd try to switch to a different song, but as soon as I stopped concentrating, I'd find that I'd shuffled back again. The shifts were ten hours long. No help came.
*It's not like I'm overly fond of that song or anything, either. There's just no explanation for it.
