You and I probably have different views and opinions on it because I am a Muslim and from our discussion I assume you're not.
My opinion is that anything outside of worshipping the One God alone or believing anyone but God can predict the future, bring you fortune, etc comes from Satan, hence Satanism.
So
Juju
Black magic
Worshipping men, animals
psychics, horoscopes
Voodoo
Charms
Amulets
Asking jesus to help you
Asking Muhammad to help you
Asking a saint to help you
Carrying a necklace or four leaf clover for good luck
All of those things are satanic in islam. Hope I didn't offend you, just sharing my belief.
