Where he goes into the studio, raps/sings and doesn't arse around with that Auto tune......
He only really used autotune in 808's&Heartbreak. I mean maybe in some other parts of other albums (not sure) but definitely not enough to get annoyed at. But then again didn't see why people were so annoyed at his use of autotune in 808, I mean, it's not like he's making a career over properly singing. He was trying something different and it didn't work out as well as his other albums, but it wasn't anything to complain about. Listen to My beautiful dark twisted fantasy, it's completely different from 808.
edit: just realised there's autotune in lost in the world, but don't worry he's not trying to prove he can sing.
