I am not, in any way, shape or form, a fan of Katy Perry's music. I find her to be a dull and uninspired. And please don't get me started on Kesha.
That said, it annoys me to say that I really love this song. The Floria Sigismondi-directed clip is visually stunning and has to be one of her best videos to date. Considering the fact that the song just hit number one on the Billboard charts this week (the fourth one of her album to do so) and the video just came out, I expect this single to be huge for her. Kudos.
