It's around the time that the back of Marcellus Wallace's head is talking to Butch Coolidge that we realize that the soundtrack to Pulp Fiction is truly no joke. The scene plays out as Al Green's "Let's Stay Together" flows coolly beneath the dialogue.
As someone who was in college when Pulp Fiction broke, I can tell you that it was the universally accepted background music to every dorm room get together. Tarantino's ultimate mix-tape of surf rock, funk and 70's soul was one of the few things that absolutely everyone could agree upon.
