In late 2010, Justin Timberlake and Jimmy Fallon performed a medley of hip-hop songs starting with Sugar Hill Gang and ending with Jay-Z and Alicia Keys. Last night it happened again, this time starting with Kurtis Blow's "The Breaks" and featuring a rousing ending on Biz Markie's classic "Just a Friend." Again, I take issue with calling this the history of "rap" and think this is really a history of "hip hop" (read more about what hip hop is here), but perhaps I'm just showing my nerdcore roots. According to Soul Culture, this is the song breakdown:
