Katy Perry's 'Prism' Is Streaming Now, Is The Best

Hear her roar: Katy Perry's new album, "Prism," is streaming right this second. Hooray! The 16-track record, which is out on Oct. 22, is the kind of hit factory that will keep pop radio in business well into 2014. This thing is a smash, with at least eight songs that could have played over the closing credits of "The Cutting Edge." (That's a high compliment.) Tracks approved by HuffPost Entertainment include all of them "Roar," "Dark Horse," "Birthday," "Unconditionally," "This Is How We Do," "Ghost" and "It Takes Two." Listen to "Prism" below.
