Watched the performance. It was basic, and, although she sang on key, her vocals were weak and sounded very thin. She struggled with the long note as usual, but at least it was better executed than the one @ the VMAs. She only sounded good in the ad libs at the end, and, unfortunately, she did not do many ad libs. Can't say I'm disappointed 'cause I didn't expect better. I'm ready for the promo singles.
