What actually happens when a song is “stuck in your head”?
In: Biology
The actual phenomenon of this is called ‘[earworm](https://en.wikipedia.org/wiki/Earworm)’.
Though not concrete, it is said earworms are correlated with music exposure, but could also be triggered by things that remind you of the song (seeing a word that is in the lyrics, hearing notes from the song, feeling an emotion that you associate with the song).
