I am old so my opinion probably doesn't help you much.
My taste in Metal leans more toward Motorhead,Judas Priest, Metallica (up to and including "Master"), Maiden, Accept etc. As I said I am old so "new" is a relative term for me. I do like "Jorn", Avenged Sevenfold (select songs), Malice, and I have given a listen and don't hate Killswitch, Lamb of God
i really don't get into most of the modern imagery. I either prefer the spartan, stripped down look of early Metallica shows or some of the "rock opera" look of an Iron Maiden show.
I draw a pretty fine distinction between Metal and Hard Rock. Much of what gets lumped into metal today actually is hard rock in my opinion. I really like "Five Finger Death punch" but do not consider them metal.
If I could have a "metal wish" it would be for Burton to come back to life, completely piss off the rest of the original members to the point they were as angry as they were in '81 and replicate the enormous hateful sound of "Kill 'em All" on some new music.
