You know, that song that keeps playing in your head. They are also called Sticky Songs or Involuntary Musical Imagery. Do you get these often? The worst ones are when you are in a store & the music is playing. Then you get home later & that song is just stuck in your head. How do you get it out? The only trick I've learned is to replace it with another song, preferably one I actually enjoy. Or, just let it run its course.
Anybody ever had one & you don't remember where the source was? You just starting singing or humming the song lol
