I would take the dire warnings from other parents of occultism in music with an
enormous grain of salt. It's largely done to
sell records to teenagers who need a way to rebel against their parents. This has been going on for
many decades. Every few years, new people come along to "save" concerned parents and their kids from the "evils" of Rock & Roll (or whatever music of the day). Funnily enough, the people at the top making the accusations often want the attention and cooperation of said concerned parents and the community/political sway that that brings, and/or donations to support their cause. (I have little doubt there's a group somewhere now explaining to each other in ominous tones how fidget spinners are a tool of the devil.)
Banning kids from listening to it will just increase its allure, and their conviction that their parents "just don't understand", and they'll find a way to listen anyway, and they'll hold onto it ever more tightly. Better to take some time to
discuss with them the imagery involved, and how you think it isn't real (I'm a fan of logic and reason as well, but I still think the Rolling Stones' "Sympathy for the Devil" is an
awesome song - in the top 100 ever written).
(For some fun, related reading, look up
Backmasking, which started off with people playing records backwards, going into it certain that they'd find satanic messages - and guess what, they "did", sort of... in the same way that if you look at clouds long enough, you can "see" bunnies and faces, our minds "find" patterns that aren't really there - see also
Pareidolia. After "concerned parents" brought backmasking into the public's eye by suing musicians over words that weren't actually there, a lot of musicians started added backmasked messages on purpose, either silly/snarky messages or occult things - again - designed to sell records to people wanting to "find" a dark secret.)
