Derek and the Dominos' "Layla" in Goodfellas
Film Released: 1990
"Layla" wasn't initially a hit, but today it's widely considered one of the most beautiful love songs rock music has to offer. So it made for some delightful irony when Martin Scorsese used it to soundtrack a sequence filled with bloody corpses hidden in trash bags and bodies frozen so stiff that they had to thaw out. Remember kids, sharing is for suckers. It's better to just whack all of your friends.
