Trouble me. Please! Trouble me!
I've had a song stuck in my head for almost a whole week. That's all I've got to say.
The remedy for getting a song out of the head is to find it, add it to iTunes library/upload to MP3 player/burn it to a CD, put the song on repeat, and indulge in a 3-5 day long sing-a-long. By then, you should be tired of the song or you will have the misfortune of having a completely different song stuck in your head.
If you experience the latter, follow the above instructions.
