What song do you sometimes hear that reminds you of a scene from a movie or TV show?

Is there a song that you hear from time to time that always reminds you of a certain scene from a movie or TV show? Or does it just remind you of the movie/show as a whole?

What song is it and what scene is it from? Does it make you nostalgic? Why do you think you are always reminded of it? Because it was an important, scary, emotional, dramatic, etc… scene?

Is there a song that is not even played during the movie/tv show, yet still reminds you of it? Why?

Please don’t mention movie or TV show themes as those are obviously going to remind anyone of it, since it was made for it!
