PopCap shares Crazy Dave’s rap

Seemingly appropos of nothing, PopCap has released a new Plants vs Zombies video featuring a rap by the one and only Crazy Dave.
To the best of our knowledge there isn’t a new Plants vs Zombies game on the way, and the title has already been released on every platform known to mankind. An optimist might suggest this video has just been released for fun, but any rational mind knows that nothing happens in marketing without a reason.
Maybe this is all part of a meta-experiment to see if games sites will post anything as long as it’s tangentially related to a videogame. In which case … damn. You win this round, PopCap!
