Definitely hot.
Geez, I had such mixed reactions when I realised what song the title referred to. I hate Katy Perry and I hate the original song (no offence to her fans)... Her music just reeks of arrogance to me. Your version is much more enjoyable and really reworked it into something with a great atmosphere and a hit of energy. This is something I can not only tolerate listening to, but ENJOY listening to. If I was a dancing type of person, I would dance to this. Thumbs up.
(Also, this song is currently the theme song for a cooking show called Masterchef in Australia. I couldn't get the kitchen out of my head lol).
