Why Do Some Songs Stick in Our Heads?

An earworm is a song that gets stuck in your head and plays on repeat. It feels like the music is living inside your brain. You might hum it without even trying. This happens because your brain loves patterns.

Your brain is like a radio. Sometimes, it picks up a signal from the past and repeats it. A catchy tune has simple beats that are easy to remember. When you hear part of the song, your brain fills in the rest automatically.

Chewing gum can help! This works because moving your jaw uses muscles connected to speech. Your brain thinks you are about to sing or speak, so it stops looping the silent music. Other times, listening to the full song finishes the loop and sets your mind free.
