The reason why no black metal band has had the success that Metallica have had is because they're not creating music deliberately aimed at the mainstream.

Black metal bands such as Darkthrone have even refused award nominations because they don't want to be part of the mainstream music industry. I doubt that the vast majority of black metal bands could give a toss that they're not as successful as Metallica.

Also, commercial success should not dictate how good you think an album is. There's plenty of black metal albums that I'd rather listen to over Metallica's classic albums.
