Why Do Some People Hear Music in Their Head on Loop?

An earworm is like a tiny music bug that bites your brain. It happens when a song gets stuck in your head and plays over and over again.

Imagine your brain is a radio. Usually, it picks the station you want. But sometimes, a catchy tune grabs the knob and refuses to let go. This is especially common after hearing a popular song or even just remembering a melody.

Your brain loves patterns. When a song has a simple rhythm or repeated words, your mind tries to complete the pattern like finishing a puzzle. If you are bored, tired, or thinking about nothing in particular, this little music loop starts playing automatically.

Chewing gum can help! The small movements in your mouth mimic singing, which tricks your brain into thinking it has finished its turn. Also, listening to the rest of the song gives your mind closure.
