First things first, The performance was FIYAH! This is one of the best performances of this sone that he has done thus far. His moves were sharp and right on time. His voice wasn't the best, but we all can clearly see why. Which brings me to this....

Sit your RETARDED sounding hating ass the fuck DOWNE!
How the hell did he rely heavily on backing vocals when it was barely ANY and all you hear is Usher live? Usher got up there and danced the dance of LIFE and you expect his voice to sound EXACTLY like the CD? Outta here! Clearly, YOU don't know anything about the music industry or about the art of performing LIVE. Jack ass. But wait, did you REALLY set Beyonce as a standard? Beyonce tosses her hair, coochie cranks and winds her hips on stage. That's not physically demanding. That's KNOT dancing. Most people lip-synch when they have hardcore dance routines to do, but Usher did it live.

FACT: MJ lip-synched more and more after the Dangerous tour and at one point only sang his ballads live and nothing else.

Please, get your facts together and stop sitting your fat ass behind a monitor mad that Usher doing what your big Gobstopper shaped ass can't!
End.
