Album: The Marshall Manthers LP2

Few songs this year had as clear a purpose as Eminem's "Rap God." Taken from his The Marshall Mathers LP 2, the song is an open declaration of Em's dominance on the mic. No verse better accomplishes this mission than the dizzying final stanza, which finds Em spewing venom for three minutes and twenty seconds straight—substantially longer in this one verse than most rappers rap on their entire three verse songs.

Within the seemingly never-ending verbal waterfall, Em touches on just about anything he could, should or would: his underground origins, the criticisms of his lyrics, the positive power his words have had for so many, and pop culture references. It's all done with impeccable technical tact, including a brief section of triple time mayhem. In other words, this verse captures exactly why the man's become a Rap God.
