It is a really touchy subject for a lot of people sadly. They are obviously Nu metal. They pretty much invented the genre and laid out the framework of all many other Nu Metal Bands. But For some reason, people keep classifying it as "rock" which just, isn't true at all in any form. They aren't rock, metal, alternative metal, rap-core, hard rock, or anything like that. The only classification that they can actually be described by is Nu Metal. So it should be that way on the article. 75.139.103.133
