I've found a link of Madonna's performance at the 2012 Super Bowl halftime show, it's at the bottom of the post. The show was nice, but Madonna is just washed up, she's just as Michael Jackson was in the late 90's, we all knew he had been great, but he was just another freak.
I don't know what was Madonna thinking when she made that extravagant show in front of one of the most conservative audiences in the world (it's the Super Bowl, not the NBA), but we've seen even worse at the Bowl. This was a nice way of advertizing her new album, but little else.
Here's the youtube video that shows Madonna singing at the 2012 Super Bowl halftime show.
