The third single off Kanye's masterful MBDTF was this all-star affair featuring Jay, Ye, and Rozay—all at the top of their respective games. Legend has it that at least one of these gentlemen proclaimed NIcki Minaj's schizophrenic scene-stealing verse to be the hardest lines spit by any female MC ever. That's a big statement, but Barbz's barbed bars back it up. As battle lines go, "First things first I'll eat your brain" is pretty tough to beat. Rob Kenner

Best Verse: Nicki Minaj
