Frequently I hear people say (and myself included) that "darn it, I can't get that song out of my head!".

Are there any studies that examine this phenomenon?

Such as what factors are involved in some people to get a certain song stuck in their head and not others. When it is more likely to occur, why the same song gets stuck for one prson and not the others, methods to stop it, relation to other issues like OCD, when it is considered not normal, etc....
