It has crossed my mind that if you only ever listen to good music then you never have a problem with an "earworm". Having Bach, Mozart or Beethoven going on in your head is a pleasure. I'll make an exception for Fur Elise. I don't know who Elise was but she must have been really annoying.
Mum's alarm clock plays an electronic version of Fur Elise.
The problem is that Mum's hearing is defective, to the point where she cannot hear the alarm.
So it rings, and rings, and rings.......
I can usually hear it when I phone her.
