I have the same problem with the song "The Entertainer." You know, the piano song. Except, I can't listen to it without getting a headache. It really sucks, because they play it almost non stop at the front entrance to Six Flags, and whenever I go, I almost always have a headache by the time I get in the park. I have my psychology class tomorrow (I'm a psych major as well), I'll ask my professor if he can recommend anything. One thing I do know, which is completely irrelevant, is if you have a song stuck in your head, the best way to get it out is to sing the entire song through start to finish.
