well if the music is evil it can't be categorized as christian. lol. Skillet is good, but they're not really screamo. yeah John Cooper has a raspy voice but there's a difference between a raspy voice and screamo. anyways, drawing the line would be between whenever it's just plain out wrong things you're listening to. Like songs completely about sex, money, etc. aren't something u wanna listen to, right? But let's say a band like War of Ages is singing, are you going to condemn them when they're preaching the Gospel and they're glorifying God with it? I mean, it seems silly to me whenever people say things like rock music, screamo music is wrong. Yeah, it's different but different doesn't mean wrong. So you just have to pay attention to what the lyrics are about.
