Sorry folks, but the absolute worst song of all time for getting stuck in one’s head is none of the above. In fact, I will put it in a spoiler box; don’t look unless you’re fully prepared to perform some kind of mental Heimlich maneuver to dislodge it from your mind’s esophagus:
“It’s a Small World After All.” That Disney song.
(Also I just learned how to do spoiler boxes and wanted to try it out.)
My secret weapon for stuck songs is to start singing Iggy Pop/Iggy and the Stooges songs. “Funtime” and “I Wanna Be Your Dog” usually do the trick and don’t get stuck themselves.
