I liked Adam at first and am kind of indifferent right now. He just needs to really bring it. I hope he does. I don't know how The Fugees are going to fit into the theme nights or even if they will. I could see him doing something from K-OS or Gorillaz too. In case anyone doesn't know who they are...

With the right song choices he could really do something cool. He could even sing 'Crazy' by Gnarls Barkley.
