It's here.

I'm SO sorry I'm late on this. I've kinda been listening to this for the past 48 hours. I got a tweet that the song was released early RIGHT before I was getting ready to leave for school and I'm so glad I text follow as many people as I do. I can't imagine waiting six hours to hear this GEM.

It's not what I expected-in a GOOD way. I NEVER know what to expect with Britney and that's what people underestimate about her. The way she completely turns around the current sound of pop music and sends it into a new direction. (That dub step breakdown--DEAD.)

Some non stans asked me why her voice sounds weird/so high. I told them they needed their ears checked. Her voice is STRONG. Not shy as it's been the past two albums. I can see her belting this baby LIVE. It has everything I love in a pop song: European dance influence, a killer dance break and a GORGEOUS chorus.

Oh by the way, it's number one on Itunes in 17 countries currently.

I would say she's back, but she never really left did she?
