Bah , I am really getting tired of these questions in the real world or forums.
Metal will never die . Simply because trends are something like fashion which dies out after something new comes up.
where is grunge ? Where is nu-metal ? where is hardcore ?
Those are few genres which were told will hurt metal.
Those genres are a trend mainstream corporate market in which kids get into thinking it is metal. After some time listening to this crap kids grow up and understand the meaning of metal , therefore they stop listening to the shity mainstream crap.
Bands stating they are from a specific trend genre mysteriously change their style into more mainstream, why is that ? Thats cause this genre they were into died out.
But metal is , was , will stay metal , in every sub category regardless the mainstream bands.
I could rant about this for hours and make a whole article but I dont see the point. Kids learn on their own , so do the bands corrupting metal with their pop elements and their stupid mainstream music.
