Katy Perry's new album PRISM is dropping in just a couple of weeks, and she's continuing to tease us with more music. With 'Roar' she lost me. With 'Dark Horse' she brought me back and gave me hope. With 'Walking On Air'? I am now as big of a fan as I was back during the One of the Boys era. The new track is completely different than anything she's released before, and coupled with the other two tracks, PRISM is going to be a very diverse album. The cool thing about 'Walking On Air' is that is has a very '90s sound which is a lot of fun. Katy channels the dance the floor divas like Whitney Houston with the house beats and general danciness of the song. I'm in love.
