I listen to my CD's, all 500+. I have a friend who owns a store that specializes in metal( thrash,death,black etc.) so I just swing by time to time to see whats new out there.
I usually listen to www.thrashnbash.com . They play hardcore, thrash,grind-whatever style of metal or punk you can think of, except nu-metal and that shitty pop-punk crap.
