Brandy's mess performance

I thought Brandy had put her wreckage days behind her. Obviously not with a performance like this. I love Brandy, but I can't defend or justify that on stage shambles. There was a technical hiccup which explains why she wasn't singing in time with the music, but that doesn't excuse her iffy vocals, hitting of band notes and her horrendous weave. Ray J jumping and down the stage certainly wasn't making the performance any better neither.
