Thanks! mystery solved! I thought it was a little slow for floor but whoever went after her also had slow music. I wish I could have seen the routines. I wonder if NBC online has the videos.
They showed her routine when I watched it live here. It is pretty cool, not your typical floor routine music, but it suits her well since she's a bit older and more mature than the rest.
I wonder if she chose it herself? I love Pink Floyd.
