Just this morning, our October cover girl, Katy Perry released her latest single “Walking on Air” . Following her hit “Roar”, this newest track from “Prism” (set to come out Oct 22) has a distinct ’90s house sound, which is nostalgic yet refreshing. It even brings me back to the days of tuning into MuchMusic to watch space-pant and crop-top clad 20-somethings dance to Love Inc.’s “You’re a Superstar” on Electric Circus. Take a listen and tell us what you think!
