Some film directors are masters at choosing music & songs to accentuate the emotions and poignancy of a scene. Kubrick, Tarantino and Scorsese come to mind. Often times, this forever alters how we hear and appreciate that song (I have never heard "Singing in the Rain" the same way after A Clockwork Orange).
I have David Lynch to thank for this one:
What other songs have movies forever changed for you?
