I believe much of what was said in the article linked to here. However, I must say that if one wants to be effective in convincing those "in the trenches" of the rock and roll music scene (and that's who we're trying to convince, aren't we?) that it is evil and dangerous and will exact a very heavy price on their souls ... I think it's important to not make silly mistakes.
Even if it's not THE most important part of the argument, a fan of the Rolling Stones is going to be amused or offended or both by reading their famous song "Sympathy for the Devil" called "Sympathy for Satan." That's basic stuff that can be checked.
This is why it's important not to embellish things for dramatic effect. You don't have to do that to make your point. You need to come across as one who knows about these things and takes them seriously.
There is enormous power in the music scene. People are heavily addicted to it. They take their idol worship very seriously. They memorize lyrics, can detail albums and in which years they came out. They read all the interviews, watch all the videos, go to all the concerts. They need to be treated with respect, even if they're choices are really bad. We're trying to convert them, not tell them how stupid they are for admiring this music and these performers.
I appreciate the warnings from church leaders to the church faithful. But if you really want to reach the ones' who are in this rock culture, I think it would be better if they could hear from someone who knows this scene. Who's come out of it alive and repentant. Someone who knows Mick Jagger is from the Rolling Stones, and what songs he sang.
Either that, or at least do some solid research and be careful about the details.
