Chuck D wasn’t saying that rap is non-fictional. He was saying that rap has non-fictional roots and that examining those roots is something that should be encouraged, not dismissed. Kanye rapping about trying to get a friend to hook him up with girls and that friend telling him to pump his brakes and drive slow — that’s real. 50 Cent saying that he’ll say anything to make his girl laugh, including “I love you like a fat kid loves cake” — that’s real. Killer Mike and NWA rapping about police brutality, Snoop and Kurupt slathering misogyny over funked out beats, Jean Grae kicking punchlines that make your head nod, Eminem talking about his relationship with his mother — those are all real, no matter how fictionalized they may be.
