Why do certain songs get stuck in our heads repeatedly?

Certain songs get stuck in our heads because they catch our attention and repeat themselves in a way that feels fun and easy to follow.

Imagine you're playing with a toy that lights up and makes sounds, it's catchy, right? That’s like how some songs feel. They have rhythms, which are like the beat of a drum, and patterns, which are like shapes you can easily copy or draw again and again.

When you hear a song that has a repeating melody, it's like hearing the same tune over and over, just like how your favorite toy makes the same sound every time you press a button. Your brain starts to follow along, almost like it’s dancing with the music.

Also, some songs have words or phrases that are easy to remember, they're like little rhymes you can say out loud. That's why you might find yourself singing them in your head while walking to school or brushing your teeth.

It's kind of like when you learn a new game and keep playing it again because it feels good, songs do the same thing, but with sound instead of action!
