I have had “Sheep go to Heaven, Goats go to Hell” by Cake stuck in my head for about a week. (“as soon as we’re born we start dying, so you might as well have a good time”).
One way to drive out an earworm is with another earworm.
Like… Yellow Submarine.
Or… The song that doesn’t end (it just goes on and on my friends).
Or… It’s a small world (after all)…
Hey Baby by No Doubt works wonders, as does MC Frontalot
What are your (least) favorite ear worms? How do you drive songs out of your head?
