AC/DC top moment was Dirty Deeds Done Dirt Cheap imo.
Have you listened to AC/DC? It's way more than one riff. The drum pattern? Yes, it's the same, borderline identical 4/4 beat over and over. But you'd have to be tone deaf to call it just one riff. I'm also sick of the people who claim AC/DC songs stick to the same 3 chords and nothing else. I'm not saying they're masters of a bajillion different chords, but you're full of shit if you think it's just three chords. The title track of For Those About Rock has nine different chords for instance.
Nu Metal is a perfectly valid subgenre of Metal.
I did actually. That was a long fucking time ago! I'm surprised you remember but I guess the name is pretty unusual.Your name seems familiar; did you post on the Gauntlet back in the day?
Ranking of each genre's overall metalness in order from most to least:
Trad metal
Power metal
Thrash metal = death metal
Doom metal
Groove metal
Non-prefixed black metal
Prog metal
Metalcore
Alternative metal = nu metal
Goth metal = folk metal
Prefixed black metal
I'd say a lot of extreme metal has surpassed trad metal in terms of metalness. It's like evolution.
