[Psychology] Why do people like listening to the same songs over and over?

I've noticed that we tend to gravitate to a handful of our "favorite songs" and listen to them repeatedly. Why is it that people like listening to these few songs over and over? At some point we can play the songs in our heads from memory!

Some people with ADHD and ASD become easily fixated on something they enjoy, and can stay glued to it for hours. In some ways, this is like stimming - a comforting or pleasant repetition. People with ADHD, for example, can be fixated on a video game because it gives them instant gratification (delayed gratification is a central problem for ADHD). Likewise people with ASD tend to like routine, familiarity, and comforting repetition. Playing a song you like repeatedly gives you predictable sensations - the opposite of sensory overload.
