The term "Nu metal" makes any real metalhead's stomach twist in disgust. In case you are unfamiliar with nu metal, it is a simplified approach to extreme metal music that has been popular in the US for some time. Bands of this genre include: Korn, Limp Bizkit, Chimaira, Soulfly, Disturbed, Drowning Pool, Static X, Deftones, Mudvayne, Flaw, Dry Kill Logic, Slipknot, ... It's also referred to as "modern hard rock" or commercial metal. It can be argued that these bands are completely talentless, since their music contains absolutely no depth whatsoever, but that is just my opinion.
There are two Nu metal bands, however, that do kick ass: Devildriver(due to their influences from real forms of metal), and System of a Down(which have some very good songs and very boring ones). What do you think of this music?
Oh yes, and if you are still unsure of what Nu metal is... read this.
