Will...did you record that off the TV with your recorder? No comment. Anyways, I don't see wut lip-syncing? I was watching this performance from a TV in ATL and I didn't catch anything, but the usual "technical difficulties," which has even happened to the -gasp- "LEGENDARY" Beyonce.
^ Yes it's true, there were difficulties that's why the background was too loud and everything wasn't right but that's ok it wasn't her fault. Besides, this is just her first performance, it will get better with time. And you're right, even the great Beyonce had this happen to her at the 2003 EMAs when the backing track kept skipping. Stuff happens.
