Did someone say Auto Tune? Haha, it's not T-Pain, dont worry. It mocks people that use it. One more, these three are the future of hip-hop.
I'm more on Emmitt's side on this one. What Wayne puts on the radio is not the same as his mixtape stuff. He knows what sells to the masses and is smart for doing it.
Also don't kill him for the guitar playing. The fact that he can is rare in rap. People kill rappers saying they aren't musicians but one of my favorites, BoB (he's in the video I posted at the beginning) plays guitar; electric and acoustic, french horn, piano, and at least one more that escapes me. It's good for rap that some of these guys are showing they have other musical talents.
Oh and I hope Kanye chokes on his mic one day. I hate that dude.
