Oooh! Look! Another video has premiered on the internet! And it looks expensive too! In the age of rampant illegal downloading, how on Earth can these poor record companies afford to spend so much on a promotional video of a song no-one will end up buying?!

Probably something to do with the fact that people actually do still buy records and the whole ‘illegal downloading’ thing doesn’t seem like much of an issue these days.

Anyway, the latest popstar to show off their expensive video is Katy Perry with her ET track which features humble rapper, Kanye West. And of course, we’d like to poke it with a stick like the rotting body of a Roswell finding.
