Remove the shock value from MMLP and this would be a complete no contest. Lyrically Eminem hit his peak in 2002/2003 between The Eminem Show and the 8 Mile Soundtrack. He was putting on a lyrical clinic on that album. Crazy ass rhyme schemes, internal rhyme, etc.

Saying Goodbye To Hollywood, Til I Collapse, Business??? This is my pick, no doubt about it. And as far as all of his lead poppy singles (My Name Is, Real Slim Shady, etc), Without Me is probably the only one that's actually listenable today.
