Yeah, the list of recommendations is a collection of personal favorites, I do realize that, and there's nothing wrong with that.
I'm not saying that the list should be strictly tracks from the early Norwegian black metal scene, vice versa; if you would want to showcase diversity, there would be classics, along with tracks further from the earliest releases of the bands. Skipping Helvete/Deathlike Silence Productions in a list like this seems odd, as the influence is unquestionable, and how diverse can you get with discographies of Bathory, Arcturus, Ulver, Burzum, Samael, Satyricon, (to name the few from your list which seemed to catch my eye), if the intention is to *get to know black metal better*, in a diverse way! Get my point now?
