Why Do Some Songs Get 'Stuck' in Our Heads?

Have you ever heard a song on the radio and then hummed it all day long without even trying? That is called an earworm. It feels like the song is trapped inside your head.

Our brains are like music boxes. Sometimes, a small part of the brain gets stuck in a repeat loop. This happens because some songs have simple, bouncy tunes that are very easy to remember. Think of it like a hamster running on its wheel. The hamster keeps going round and round until you stop it.

Listening to the whole song can help because your brain finishes the job. Eating chocolate also works for some people! Another trick is chewing gum, which confuses the part of your brain that sings silently.
