If You Keep Singing That Song, You May Have An Earworm

How many times has it happened to you...?

You hear that song you love and it plays in your head over and over, all day and maybe even all week long. No matter what you do, you can't stop it. It can drive you a little crazy!

So what causes that? You may have an earworm!

MSN reports that a University of Montreal study said that it's kind of scientific, and some songs are 'stickier' than others. To get rid of it, experts say to concentrate on something else.

If this is all true, then you can catch an earworm from Lady Gaga at any time. Scary thought.
