Another great thing about "Mean Streets" is how Scorsese used Fifties and Sixties music. Starting with "Be My Baby"--perfect complement to those home movies. And "Rubber Biscuit" by the Chips for the party scene. And "Florence" by the Paragons while driving to the poolroom--quintessential NY doo-wop. But the best, IMO, was Charlie trying on the monogrammed shirt so admiringly--and the Chantels' "I Love You So" playing as Charlie loves himself so.
