12. The Roots f/ John Legend "Doin' It Again" (2010)
Album: How I Got Over Producer: Richard Nichols, Black Thought, Questlove, Dice Raw, Rick Friedrich Label: Def Jam/Universal Lyric: "Doin' it again just like Poitier and Cosby/I'm like Martin Luther King; you like Rodney/The difference is I give it everything inside me."
With a name like Black Thought you know you're dealing with a serious MC. So who better to liken himself to than a serious orator like MLK?
