For all the shit Britney gets nowadays, her singles have always been top notch. Even when her vocals were long ago deemed utterly fake and her persona as manufactured as a slice of American cheese, a fan would always have the singles: the sensual “I’m A Slave 4 U,” the clever “If You Seek Amy,” the absolutely perfect “Toxic.” And here is Britney trailblazing pop yet again with a single that blows most of Circus out of the water. Britney does dubstep, something I couldn’t believe until I verified from multiple different streams. Listen to the whole song (it’s really good!), but the bridge around 2:05 almost made me fall off my chair.
