I get songs stuck in my head alot. Boy is it annoying! Not only songs but thoughts, phrases, commercials, etc. When it happens I usually end up having an anxiety attack because it gets on my nerves so bad. This happens to me mostly when I am alone and bored, like when I am driving. I try everything to get my mind on something else. Dont worry, you're not the only one! Hang in there and Good luck.
