Wow, that medley performance is pretty bad. It didn't quite come off like I think he wanted it to. No momentum, and it fell a bit flat. He should have just picked one of the songs and rolled with the full thing. For example, if he would have just done "Jesus Walks" all the way through I feel like it would have been way stronger and more memorable.
He sounded awful when he tried to sing on "All Of The Lights" and clearly cut himself off, and he sounded like shit on "Black Skinhead" too, which is the best rock song ever written by a hip-hop star.
