29. Nicki Minaj feat. Eminem, "Roman's Revenge" (2010)
On "Roman's Revenge," the throwdown between two of the 21st century's most technically proficient crossover MCs, Eminem and the then-ascendant Nicki Minaj trade barbs (and au courant references to iPods and Giants quarterback Eli Manning, as well as a shout-out to Busta Rhymes' verse on A Tribe Called Quest's "Scenario") over a malfunctioning-Nintendo beat crafted by Swizz Beatz. "Absolutely the most fun song on Pink Friday – it gave me life, dahling," Minaj said, in her Roman Zolanski persona, during a 2010 MTV interview. After clarifying that she collaborated with "Slim Shady" not Eminem, Minaj was asked who offered up the "crazier" character. She broke up laughing and exclaimed, "It has got to be Slim!"
