Mess. DH has everything to be a classic.
It was commercially HUGE, popular across multiple formats, global, generally well received by critics, fantastic longevity, AND the most important factor in it being a Katy classic; it sounds nothing like any of her other hits. It stands out in her catalogue. I know several people who hate Katy but will blast that **** so loud you can't think straight.

But I've made my case for it. I guess we'll just have wait for some to accept it as her fifth classic.
