@ Dan Bofficial, Okay you do have a point Usher was singing live before (and sounding great) and maintaining a high level performance and your right Bey does do both with ease. There are many who can't and for the most part that should be a goal.

I think Usher, however dances much harder than anyone in the game right now (with the absence of C.B.) I don't think it's fair to expect alot of strong live vocals when he's practically doing everything but back flips. He's a little older now and he has to match all that he was capable of doing before or even step it up a level. I cut those kind of artist some slack. Even MJ wasn't doing some of those acrobatics (don't get me wrong he's still the inventor of popular dance). It's just gets to a point where you can draw the line and give some people a break.
