Countless producers have jacked different pieces of David Porter's "I'm Afraid The Masquerade is Over," from his 1971 concept album Victim of the Joke? An Opera. Here are a few notable ones. My personal fav is Rza's usage of the opening pianos for Gza's "Duel of the Iron Mic," although the new Freeway joint, "It's Over," is a good flip.
