???????Deadmau5 ( Wikipedia says...)? At the end of the Grammy's there was a very strange final act including David Guetta (a DJ I think), Lil Wayne, Foo Fighters, and Chris Brown. I was not sure about that, really and was more than willing to change channels at that point. When did I become OLD! There used to be a day when I knew every artist and usually had all their CD's. I am so out of touch and I'm just not happy about that.
