For something that's labelled "90s: The Essentials" it misses out on a whole heap of stuff that most metal pundits would regard as essential and focuses too much on crap obscure Black Metal wholst ignoring key genres of the period (e.g. Groove and the Power Metal which hit a peak in late 1990s as well as large amount of pivotal DM albums from the early 1990s).
Yeah, I guess you have a point seeing as "the essentials" indeed comes off as more objective than "my favourites", for example. Creating a general metal list of 90's essential albums, so covering all genres, is pretty much impossible. I can also easily name a ton of albums that I think belong on this list, but I previously judged the list on the albums it features. And there's simply lots of great stuff on here. So to sum it up: it's a great list, but calling it "the essentials" isn't the best title for this list, even if it's subjective.
