Listen up, Katy Perry fanatics, the pop superstar's hotly anticipated third album, "PRISM," is now streaming in full on Perry's official web site.
Perry addicts who have been living off of latest No. 1 hit "Roar," the Juicy J-assisted banger "Dark Horse" and Stockholm-born disco ball "Walking On Air" can now hear new single "Unconditionally," recently leaked jam "Birthday" and the tearjerker "By The Grace of God," among other "PRISM" colors. The follow-up to Perry's "Teenage Dream," which spawned five Hot 100 chart-toppers, is due out officially on Oct. 22 through Capitol Records.
