UPDATE: Now that Gaga's new single "Applause" has dropped a week early, you tell us; Whose single is better - Katy's or Gaga's? Vote now!
"Roar" is the first single from Katy Perry's upcoming album, Prism—due out October 22.

This sweeping anthem is like "Firework" with more bite and it has "Future Karaoke Standard" written all over it. So, yes, you will be screaming this into your hairbrush.
