I can't remember a time when I have not had a song stuck in my head - I go from one song to another every few days and have done for as long as I can remember (today, Whiter Shade Of Pale is just starting to leave after nearly a week of being firmly lodged in my brain, and I'm now moving on to Magic Carpet Ride). It's not unpleasant for me though - the article makes it sound like it might be for other people?
