Kanye is an insufferable ass. He does do great work sometimes - Jesus Walks was really a great song, IMO. However, when he acts like such an egomanic a-hole, he completely discredits any message he is trying to send. What a waste.
I would LOVE for Jay Z to knock some sense into him. Jay Z is amazing and has really grown into a mature artist who knows the right way to reach the masses - look at how he handled his beef with Cristal.
