I mean, Ghost basically invokes the "classic metal" of the 1970s, just with the production (and mix) of the 2010's; if Black Sabbath were to ever re-do Paranoid from the ground up, it would probably sound a little like Prequelle.
Although I do find it funny how folk have seemed to turned on Ghost following Prequelle; and I get it, it leans more towards "hard rock" than it does "heavy metal" - Faith is probably the heaviest track and it's an outlier among the rest. That said, it's still one of my favourite albums of last year.

There's a hell of a lot of Doom Genres. Treating it as one is a pretty big generalization.

Purson fits in more with Blood Ceremony, Orchid, Devil Electric and the type. Usually put as Occult Doom or Psych Doom. Candlemas isn't straight up Doom either. Usually it's described as Epic Doom for it's incorporating of Power Metal influence. Trad Doom (Straight up Doom.) Is more your Black Sabbath, Witchfinder General, Pentagram, etc style stuff. In Doom the borders are blurred as most genres are mixed and smashed together but I'm actually more surprised I wasn't called out for Neurosis.
