Santa is an anagram for Satan so good enough. Anagrams are big with Satanism too. I always liked the Santa version of winter holiday celebration instead of the jesus one celebrating his birth. Like, why do I care about jesus? All I care about is those presents Santa brought me. It's much more fun. Reindeer, elves, and magick Santa sneaking down my chimney to give me free stuff. I miss those days...
I looked up Satan band on youtube and found this. https://www.youtube.com/watch?v=_B7ZZNxxGGY
I looked at the comments section and saw someone who commented the JoyofSatan.org link lol. It's a good song too.
