It's a lip sync act. She doesn't really know any different. Suffice it say I'm glad it's not my style of music. I guess if you like dance routines and pre-recorded music that people pretend to perform, you like this. It boggles my mind that for the #1 TV sporting event for 18-49 year old men, they keep picking performers that would alienate that audience. Yeah, they've had U2 and Springsteen and Petty, which were okay, but why trot out Madonna or Britney or Janet Jackson? Makes zero sense
