Katy Perry Releases "Roar" Follow-Up, "Dark Horse"

After the outstanding success of "Roar" (No. 1 for three weeks), Katy Perry's lead single from her upcoming album Prism, the international pop star doesn't exactly need a dark horse to win anymore, but fans get just that in the release of the singer's second single.

"Dark Horse," the slow-burning R&B track feat. Juicy J., sidesteps Katy's bubblegum roots for something a little darker and more grown-up. Like "Roar," we expect it to shoot straight to the top of the charts when officially released for radio. 

But who cares what we think! What do you think of Katy Perry's "Dark Horse," Instincters?
