Britney Spears' new single, "Hold It Against Me," has already made music history by making her the second artist ever to have two songs debut at #1.
What does the rest of her new album have in store?
"It's way more edgy than the last album," says Claude Kelley, who composed several tracks for the as-yet-untitled album, referring to Circus.
HARDER: Britney Spears is gonna get gritty.
He adds that Spears is returning to the tougher, grittier sounds of 2007's Blackout. "[It's] more in the vein of the album before [Circus]," he says.
"The last album [Circus] was more clean pop. [Its purpose] was to reintroduce Britney to the world as the pop princess ... this is much edgier."
Basically, get ready for some club-worthy tracks.
"Dr. Luke and Max Martin are running the show, and it's all about the beats. It has a heavier bass line and it's harder, more urgent, more club."
