Did I miss the opportunity to throw "Work Bitch" into the ring as one of her worst ever singles?
It's pretty middle of the road to me. I still bop to it frequently, mostly when I'm at the gym or going for a run, and it works really well as the opener in Vegas. It's obviously nowhere near as brilliant as Gimme More, Slave, Toxic, Oops, etc. It's certainly no Make Me, which has quickly become one of my favourite Britney singles ever.
...come to think of it, I guess Work Bitch is
one of her worst singles, but that says more about her impressive single output. Pretty Girls and Ooh La La are the bottom of the barrel for me, but then I genuinely like or love every other single that she's released. Work Bitch and Perfume are both in the lower half of that list.
