Best use of source music

[Scarface98.9]

What do u think was the best use of licensed songs in a movie?

My personal picks go to
Reservoir Dogs-"Stuck in the middle with you"
and Goodfellas-That one song by Eric Clapton playing during the montage after the heist

"Son of A Preacher Man" in Pulp Fiction. I always thought that the music matched the scene.
