I really didn't like the preformance all that much. Maybe I just am tired of all the overproduced shows out there these days. I will say I think she was actually singing although I'm sure the backround music was canned. And it did have a lot of energy but aren't we tired of the fake crowds put around the preformer to do fake reactions to the preformance.
The Olymics did it so much better. As for the mic drop, ehhh, don't care.
