Yes indeed you have said this before and I remember because I am good at reading. Good so you know how strict the rules are and how if you break the rules a lot you're furhter down the chain or probably just an enemy agent. Music though indeed is a strong power in Discernment of the spirits and also exorcism. You could consider how easy it be to marry the gifts with the music, way better than a tattoo of a really stupid mark, not the dumbest, the 666 one holds that tile, but still you know pretty far up there not gonna lie this is I see your mad genius in it, but if you do it the way that the joke will be on you is a way you won't find funny. If you don't do it though and get thepiphany much potential already for those real powerful gifts. Think about it you want a tattoo so a coroner basically wonders about your life, but he won't, but then if you could learn how to exorcize tattoos or even get stronger than that, would't that be more worthy and legendary song for a Revelation 14 saint to sing for the rest of all of eternity?
Leviticus is still in the Bible by the way you err in trying to discard it and teach other people the same, it's not like eating pork where the penalty is to take a shower because your a pigeating metalhead,, the Law still matters according to Jesus and the Apostles. You're just not saved by it and you don't neccesarily have to draw the full punishment (in this case death penalty for witchcraft or the equivalence in penance). Keep thinking about it, don't do it, praise Jesus
