I was actually going to comment on this myself. Kanye West is a really creative producer. He specifically said with this album that he doesn't care about sales - and his fans have generally reacted poorly, as I understand it. He doesn't care that other people use Autotune - he heard it and said he liked the sound, so he's using it. I like that attitude a lot. No stereotypical hip hop claps, kicks, and snares here. Just unique production.
I've heard another track from the album, "Robocop", which is also quite creative. It uses dry orchestral strings, distorted 808 percussion, and an unusually major tonality.
