"they should know immediately what it sounds like: it has highly-distorted guitars, shrieking vocals, etc" - but what defines black metal apart from other forms of music that ALSO use distortion and screaming? punk rock and indie may well have ideologies, but black metals different values are easily identifiable and unique. you all seem intent on giving black metal a disservice by simply labelling it as angry music. if you cared about the genre, you wouldnt. and LOL at thinking burzum has no ideology, if you are the kind of person that thinks that then you don't know enough to edit this article (the problem with 80% of wikipedia)

"To someone who is a non-listener, the fact that black metal has an uncompromising ideology is rather useless as a description" - why? wouldn't they want to know? 

also nice to see the page locked. go listen to cradle of filth you complete tits, you're all untermensch
