Rakim's hyperbolic statement aside, Eminem was a high regarded MC from '99-'04. SSLP, MMLP, TES, his guest appearances, and songs on the 8 Mile Soundtrack are proof of that. Anybody that denies that doesn't understand the art of emceeing. I'm not just talking about some rappity rap, "lemme rhyme as many syllables as I possibly can" type lyricism either. Eminem actually had wit, depth (metaphors, similies and imagery that actually painted pictures). He could indeed write songs. Who cares about the opinions of people who don't listen to rap outside of Eminem (which is where most if not all of the downplaying and discrediting of Eminem comes from. It's pretty much a knee-jerk response). I think The Beatles are the most overrated group ever, but I can't deny John Lennon's pen game. Are there better writers? Of course, but that doesn't excuse the fact that he was great.
