I friend of mine has around 160gig of metal. And some is downloaded yes, but he owns a LOT of music.
Side note (kinda):
I know its an old argument, but I really do feel that downloading helps the metal scene a LOT. If I hadnt found downloads, I wouldnt own 75% of the music I have killed myself to hunt down and buy.
It's enabled me to find fantastic bands like never before, and the real beauty about it is that I can bypass the stores and order in ways which helps the bands and labels financially in a more positive way.
The only bands in general who complain about downloads are the ones who earn millions. Its not often that the lesser earners complain - they need the medium to help their material spread.
So I support downloading, but only if the EP's albums are deleted from print, or, if you plan to really support the bands and their labels by buying the music, the merch and going to the shows.
Peace.
