A playlist to discover Black Metal

There's no Mayhem in that list, which is possibly the only other major essential band I can think of. For my personal taste I'd probably add a Marduk track, but they're not exactly an essential band. And Cradle of Filth, while not considered black metal by most purists, make an easier transition for a beginner from other genres of metal into black metal.

Damn fine playlist though.

Tracks 1 - 3 as these are all things that get called 'first wave black metal' which by and large is one of the biggest myths of the entire metal genre. Bathory fits, but a lot of this stuff was just heavy metal, speed metal or thrash metal. Celtic Frost and Venom could be said to have provided the roots, but weren't black metal themselves. Others like Mercyful Fate had nothing to do with black metal. Including them just leaves the possibility of leading new listeners the wrong way. 

Also I'd take Darkspace out. Probably too advanced for a beginner listener. They're more of a 'once you know the basics' act. I've listened to black metal for over a decade and even I find their albums a difficult listen. 

As for additions, Burzum, while not to everyone's taste, is pretty much a must if you've going to cover all the basics. Filosofem and Hvis lyset tar oss are both very highly rated album (#1 and #2 on RYM for black metal, actually). 

If you want to include some melodic black metal, then some Dissection is an essential inclusion. And Windir as well. While not the roots of the genre melodic BM may prove a better gateway for many. Other sub-genres like depressive, pagan and war are for more intermediate to advanced listeners.
