Nicki Minaj knows her way around a pop song, but the rapper's most scintillating rhymes are far too brutal for mainstream radio. Just check out the threatening barbs she drops over the rumbling beat of “I Am Your Leader”, or on the warbling, tic-filled “Want Some More”. On “Roman In Moscow”, Minaj unleashes her wild alter ego Roman Zolanski, cranking her voice into beast mode to rain fire on the track's skyscraping synths.
