This article focuses excessively on 'violent lyrics', which are only a feature of some small sub-genres in the greater landscape of modern extreme metal. While no one is going to confuse the lyrical content of most metal as being upbeat or positive, there is enormous diversity of musical styling and lyrical subjects across the genre, just like any other. Most lyrics and most extreme metal bands don't focus on subjects like the article discusses (CC in particular). Death Metal (and it's sub-genres) is today more associated with musical and vocal style rather than violent lyrical imagery.
