Usher DID THAT. I actually went to the show (unlike zero budget thatgrapejuice that gets donkey of the day for posting the 3 most boring clips of a high ass energy show) and Usher was singing and dancing non-stop to all his undeniable hits. I didn't think I would even like him doing Good Kisser but I did. The last act of the show (obviously all he had to do was perform "Yeah!" and the house tore up) was phenomenal. His joints didn't have the arthritis I expected them too lol. He honestly all we've got in Vegas cause I can't sit through no damn Chris Brown setlist of 30 songs that sound alike or Beyonce trying to make b-sides like "Freakum Dress" worth my attention. My Way, You Make Me Wanna, Nice and Slow, U Remind Me, U Got It Bad, U Don't Have to Call, Yeah, Burn, Confessions Part 1, Part 2, My Boo, Lil Freak, OMG, even I Don't Mind....nobody has a setlist with that many BOPs at their show. I don't wanna hear Rihanna sing for 2 hours nor lipsync and I don't EVER wanna listen to Beyonce do anything other than Destiny's Child, Crazy In Love, and Single Ladies. Ladies get that WAP and bring it to Vegas to see the King while we still have him.
