Songworm 

A Songworm is an annoying song that you hear once and it replays itself over and over in your head until you are ready to commit suicide. Later in the day, you think you forgot about it and before you know it, it's in your head again, and you may even find yourself singing it. The only cure to get rid of a Songworm is to catch another, more annoying Songworm in your head.
