Getting a song stuck in your head can be annoying. Getting a Christmas song stuck in your head can be PURE HELL. So this is what I call perfect timing. There’s a 40-second audio track called the Earworm Eraser and listening to it can supposedly get songs UNSTUCK from your head. It’s constantly changing tempos, time signatures, and musical styles, so it won’t just become another earworm to replace the one you’re trying to get rid of.
