Choice of music, is in no way indicative of one's religious beliefs. I would never follow anyone's religious beliefs, yet listen to extremely dark, or what you label "satanic" music. I find the lyrics just as amusing as any "christian" bands. 666 are just numbers, and if you believe they mean anything, you are no different than a christian.
