Really it is no differant than any other music.They just sing about the downfall of God.Satanists really hate God.The only band I can think of of the
top of my head is Venom.The were an 80's heavy metal band that just bashed God,and quoted verses out of a Stanic bible.
No it is not addictive.Unless you have a weak mind no music is addictive or harmful.IMO....
