Well, actually the spirit they are operating in is more important than what they are saying. If they don't openly talks about the cross, the resurrection, the blood, repentance, sin. Don't say Jesus by name, giving you a "God loves you" but never tell you to repent is dangerous. But I love the way rock lyrics address things of pain, set back, calling out certain errors. I mean I just heard this some by barlow girl called "grey" calling out lukewarmness, some can be good. But if you look at interveiws about what they believe about Jesus it seems lacking. All of them seem to. These are questions I think should be asked when evaluating if this should be someone one should listen to or watch a thing. The Bible says we should test every spirit. So it's perfectly biblical to question everything.
