There's nothing worse than having an annoying song stuck in your head. Of course, that would never happen because of our show, or some of the songs we play like Carly Rae Jepsen 'Call Me Maybe', or my friend Andy's favorite song 'Thrift Shop'. But if it does, scientists have finally figured out a way to get you some peace.

Dr. Ira Hyman is a music psychologist at Western Washington University. He just finished a study that found the best way to get a song out of your head is solving a puzzle that's 'sort of' hard.

When you have a song stuck in your head, it's actually because that song is dominating your working memory.

When you force your brain to concentrate on something else, like a Sudoku puzzle or a video game, you can push the song out. But if you pick a puzzle or a game that's too easy or too hard, it won't engage your mind enough. So as long as it's sort of hard, it should work. So the next time you can't get popping tags out of your brain. Doing a puzzle is the answer in getting it out of there. So to get you started on the right foot, here is the biggest earworm of the past five years.
