How metal is your vocabulary?

Without a doubt two of the greatest flavors of the '70's and '80's is Dungeons & Dragons and Heavy Metal.
I would blast Metallica and Black Sabbath while drawing D&D characters for my high school gaming group. The imagery of metal is essential dark fantasy and naturally inspires characters, creatures, and adventures for any great D&D campaign.
A data scientist recently scraped data from over 200,000 metal songs to compile the most metal top 20 list of words. How was this data compiled?

To get the lyrics, I scraped www.darklyrics.com. While darklyrics doesn't have a robots.txt file, I tried to be gentle with my requests. After cleaning the data up, identifying the languages and splitting albums into songs, we are left with a dataset containing lyrics to 222,623 songs from 7,364 bands spread over 22,314 albums.

These words are a handy reference if you wanted to spice up the taunts of a Heavy Metal Lich "I'm gonna tear the veins from your body as you scream and pray to the gods!" or if you wanted to come up with the most metal name ever for an adventure module "Reign of the Flame Demon's Sword of Sorrow".

There was also a list of the least-metal words, but I didn't want to taint this totally metal post with those words, so you'll have to follow the link to see them.
