A: Donovan's "Atlantis" From 'GoodFellas'
Let's face it: Donovan's hippiesh ditty about an underwater utopia is the last song you'd expect to play over a brutal barroom beatdown. But Scorsese figured that the juxtaposition of this Age of Aquarius tune with the sight of loudmouth gangster Billy Batts ("Now go get your fuckin' shinebox!") being pummeled to pulp would create a gruesome sense of irony. His gamble paid off: listening to the Sixties folk singer gently coo about being "below the ocean" while a made man gets stomped, you can practically hear Tarantino taking notes in the background.
