Not much to say about this song. Also not sure what I think about Katy Perry in general. It all seems so manufactured, but I guess you have to give her props for working so hard.
You're hot then you're cold,
You're yes then you're no
You're in then you're out
You're up then your down
Those lyrics, whilst awful, remind of Dead or Alive. Perhaps if Pete Burns were singing it I might enjoy it more. But Pete is going through a lot of things including botched cosmetic surgery so unfortunately we won't be hearing that. In the mean time here is my faster sleeker version.
