Song trivia:Why do some songs keep lingering in my head?

Researchers sometimes jokingly describe this phenomenon as: "earworms". Some songs seem to be particularly easy to linger in the brain, but there is no simple rule to judge whether a song is easy to remember.

People who have studied this field have found that easy-to-remember songs tend to have short, repetitive passages that can be connected to the listener, such as a song that you would otherwise know or have a cultural connection that resonates with you. All help the song stay in the mind, but whether a song is easy to remember will still vary from person to person.

So which is the brainwashing song for you?
