Of all the acts performing at Wango Tango T-Pain and Pitbull put on the best show. T-Pain should have closed the show because he shut the concert down. Up to that point, it was good, but with so many acts it was impossible to stay in one party mood. The staging area was in a location where people with good floor seats could not see, and had to watch on the video screens. T-Pain and his dancers (especially BIGRYAT) used the entire stage to dance, sing, and rap. It was off the hook. When he came out again and sang with Pitbull, I was again amazed at his energy. I also enjoyed seeing NeYo with Pitbull. Now, Jennifer Lopez? Just saying that she is a diva. She can dance, but she was not very kind when her sound shut down. I am sure nobody did that intentially, but she said, "somebody is getting fired tonight". Really? Sorry, but nobody did that to you on purpose. The worst part of the concert is nobody said a good - bye, drive safely, or see you next year. After JLO the lights went up, and that was it. Ryan Seacrest came out once and Brittany once. So much for "hosting". It was good. I might go again depending on the acts.
