To contribute something original in this thread, a very large portion of metalheads like Pantera, I find them extremely awful. They're not 80's classics (well, someone will post about 'Power Metal' I just know it), they're totally 90's 'metal', but they're revered wide and far and I just can't stand them.
Something from the eighties... hm... well, the first Liege Lord is considered by many to be amazing, but I think they hit their stride by Master. It's not bad by any means though. A lot of US Power is overrated (at least here in greece

Also, I guess I'm doing pretty good zen-wise because none of the opinions expressed here got me irritated. Not even the Jag Panzer one.
