It's a pretty common thing to make it through part of the day and realize that you've got a song stuck in your head.  However, did you know that there is actually a syndrome that people have where they constantly hear music when there is none?  It's called Musical Ear Syndrome, and it happens quite often.

It's called a "musical hallucination" and is described by the British Tinnitus Association as "short fragments of simple melodies" that "are often mistaken for real music until it becomes clear that none is being played."  If doesn't sound so bad to you to constantly hear music, imagine what it would be like if you had a radio that you couldn't turn off.  Or even worse, if it was a song that you couldn't stand like "How Much Is That Doggy In The Window".

That's what happened to Susan Root.   She's a 63 year old custodian who says she has Patti Page's version of "How Much Is That Doggy In The Window" constantly playing in her head.  She has been told that there isn't anything that doctors can do and that she will probably be stuck with the disorder for the rest of her life.

I've heard of tinnitus which is a pretty common hearing problem where you hear a constant loud noise that won't go away but I've never heard of songs being played on a loop!  What would be the worst song ever to have stuck on a loop in your head?
