OK, I'll start with you. Please define "black metal".
Wikipedia's definition of black metal:
"Black metal is an extreme subgenre of heavy metal. It is typically abrasive and usually makes use of fast tempos, high-pitched electric guitars often played with tremolo picking, high-pitched shrieking vocals, and unconventional song structures. It is prone to experimentation and certain elements typical to black metal are not always used by every band within the subgenre."
Skipping to the more important parts:
"The most common and founding lyrical emphasis revolves around Satanic, Pagan, and/or occult themes. Opposition to Christianity is a nearly universal theme among black metal bands. War, misanthropy, and suicide are often explored. Lyrics may also celebrate environmental origins of bands, celebrating darkness, winter, snow, blizzards, forests, and other natural surroundings of northern European countries, as well as their folklore and history. Lyrical content may also be inspired by fantasy. The Austrian band Summoning focuses almost exclusively on J. R. R. Tolkien's Middle-earth for its lyrical content. Other bands create their own fictional realms (for instance, certain songs by Immortal depict a fictional kingdom called "Blashyrkh"). Bal-Sagoth's material is made up of various song cycles, and original fantasy narratives, inspired by writers like Robert E. Howard and H. P. Lovecraft."
Theistic Satanism is different from LeVeyan Satanism.
LeVeyan Satanism: "In LaVeyan Satanism the Satanist does not worship Satan in the theistic sense, but plays the role of an adversary to spiritual creeds, espousing hedonism, Randian Objectivism, Nietzschean philosophy and atheism."
Theistic Satanism: "Theistic Satanism, also known as Traditional Satanism, is a general term for the belief that Satan is an actual deity or force, and worthy of reverence or worship."
I don't see Negura Bunget or Burzum praising Satan. Nor do I see Austere or Nyktalgia praising Satan. I don't see Enslaved praising Satan, either.
