ELI5: what happens when I get a song stuck in my head?
gpt
You see or heard something that reminded you of the song. However, your brain is not satisfied just remembering the song. Your brain can't find closure and throws it on a loop. That's why listening to it usually helps; the brain has heard it all again and can end the song in a natural manner. Think about it, you never have an entire song from start to finish stuck in your head. So if you want to get rid of a song in your head, play the damn thing start to finish and you should be fine.
