I don’t know if this is a good recommendation, but if you really just want to listen to the sound of metal, I’d check out “Frog Leap Studios” on youtube. Leo Moracchioli puts up a metal cover of a pop song every week (and has been doing so for years so there are a lot of them). The added bonus for me was that he does some covers of kids songs and my kids love metal now (my spouse does not love metal, however). I’ve probably listened to this a hundred times now:
Also if you want to make sure the lyrics aren’t about anything that even related to contemporary reality, there’s always viking metal, which wasn’t even a thing when I was a kid listening to metal.
I was reading that sign “If you teach your kids to disobey God…” It’s like, if God says killing is a no-no, then I guess me and God agree on some things. It’s not like a teach my kids to disobey God. I just don’t teach them to obey God. In fact, when my kid asked me who God was, I started by explaining what a god was, because they really had no idea.
Child: Is Christmas about baby Jesus?
Me: That’s what some people say.
