James Kellaris, a marketing professor at the University of Cincinnati College of Business Administration, has done research on earworms and brain itch, and he's found that as many as 99 percent of us have fallen prey to them at one time or another [source: BBC News]. Kellaris says women, musicians and people who are neurotic, tired or stressed are most prone to earworm attacks. With musicians, it makes sense because they're listening to music continuously, but Kellaris isn't sure why women are more susceptible to earworms [source: Prokhorov].
Researchers also aren't sure why some songs are more likely to get stuck in our heads than others, but everyone has their own tunes that drive them crazy. Often the songs have a simple, upbeat melody; catchy, repetitive lyrics; and a surprise such as an extra beat or unusual rhythm -- the same factors that made the songs or jingles popular in the first place (like the Chili's, "I want my baby back baby back baby back ribs" jingle, which made Kellaris' list of the most insidiously "stuck" songs).
Most people (74 percent) get caught up on songs with lyrics, but commercial jingles (15 percent) and instrumental songs (11 percent) can also be hard to shake [source: DeNoon]. What makes us groan is cause for celebration to record companies and advertisers, who are thrilled when people can't get their songs and jingles out of their heads.
Contrary to popular belief, we don't just repeat the songs we hate. In one study done by researchers at Bucknell University, more than half of students who had songs stuck in their heads rated them as pleasant, and 30% were neutral. Only 15% of the songs were considered unpleasant.
How to Get Songs Out of Your Head
Unfortunately, there's no tried and true way to get songs out of your head once they're stuck in there. They can stick in your brain for anywhere from a few minutes to several days -- long enough to drive even the sanest person batty. Most earworms eventually "crawl out" on their own, but if a song is nagging you to the brink of insanity, here are a few tips to try:
1. Sing another song, or play another melody on an instrument.
2. Switch to an activity that keeps you busy, such as working out.
3. Listen to the song all the way through (this works for some people).
4. Turn on the radio or a CD to get your brain tuned in to another song.
5. Share the song with a friend (but don't be surprised if the person become an ex-friend when he or she walks away humming the tune).
6. Picture the earworm as a real creature crawling out of your head, and imagine stomping on it.

Don't worry if you keep getting songs stuck in your head -- it doesn't mean there's anything wrong with you. However, if you actually hear music that isn't there (instead of just thinking about it), see a psychologist or other mental health professional. It could be a sign of endomusia -- an obsessive condition in which people hear music that isn't really playing.
