I read this crazy story in dailymail.co.uk
A 63-year-old woman suffers from a rare condition which makes her have musical hallucinations.
She has had the 50's tune "How much is that doggie in the window" stuck in her head for THREE years.
Musical hallucination involves hearing melodies in your head on a continuous loop. (Earworms.)
She has been told that there is no cure and she will be stuck with it for life.
If you had to pick one song to be stuck in your head forever...what would it be? Mine would be "Hey Hey What Can I Do" by Led Zeppelin.
