Obviously, scores and songs made for movies and TV shows have a tendency to evoke a particular setting--if you think of the kind of music that goes with a Spaghetti Western, I suspect you'll think of something like the theme from The Good, The Bad, and the Ugly.
But there are others that, although they started in popular culture, have later become associated with certain scenes and settings. Classic example: Fortunate Son by CCR = Vietnam War.

Also acceptable: songs that bring to mind a specific movie scene because of their use in it (again, provided the song was not made specifically for the movie):
