I randomly have the song "Fathoms Below" from The Little Mermaid stuck in my head.

It occurred to me that the two Disney movies whose background music always gets stuck in my head at random moments are The Little Mermaid and The Rescuers Down Under. There's something about their soundtracks that struck me as a kid and never really disappeared over the years.

It's usually "Tour of the Kingdom" from the first movie and that one song that plays when the kid flies on the eagle for the first time in Down Under that do get stuck in my head. Although when I listened to them again recently from their soundtracks they seemed to have a faster tempo than I remembered them having... I guess I thought they sounded better slow or something.
