A little more contemporary would be the soundtrack for "The Social Network". Gave me a whole new appreciation for Trent, and he and Atticus deserved those Oscars for it.
EDIT: Duh! One of the most 80s movies of all has a killer Tangerine Dream soundtrack: "Risky Business"! They also killed on the "Thief" soundtrack, too...that sort of served as the template for loads of Michael Mann's later work, such as the ultimate vapor TV show: "Miami Vice".
