Nobody owns Slayer, you know as well as i do. I'm a true Slayer fan, not only because i have all their albums and i know their songs from back to front but i really like Tom Araya's Vocal. It's unique, unlike bands such as Opeth, Testament, Cannibal Corpse, Slipknot etc, where one vocal sounds exactly the fucking same from another.
I like Metallica because the combination of Heavy Metal and blues. It really is a big disappointment when i heard St Anger, i just couldn't believe it. All the lyrics are about fighting for fucking rehab and shit. James Heitfield should start drinking again and write kick ass songs. I'm not saying only the first three albums are the best and true metallica fans should only listen to such and such albums. But in my opinion, Ride the lightening, Master of puppet, and justice for all, and the black album are the pinnicle of metallica, from that onwards they just went downhill.
