Not a fan of Diane Warren. I find her very mainstream and boring with those type of power ballads she does. I can hear Gaga screaming now. I liked Gaga's earlier songs when she didn't feel the need to oversing to prove something.
I"m listening to the new Bjork album now. It's amazing. I think a Bjork and Gaga duet would be great. Imagine the costumes! I even think their voices could blend beautifully together. Gaga needs to try something more innovative and not so dull like Diane Warren. And sing in a different way, more eccentric like Bjork.
