I absolutely get what you are saying, and it's true that manipulation of emotions can cause problems. We know not everyone gets saved for whatever choices of their own. I absolutely understand that the same agenda in pop music is weaved through even Christian music. However, I believe that we are all called to Christ in different ways. God knows that what works for one person, will not work for another, and he will keep knocking on that door however way he knows will work. And he will not let anything that brings someone closer to him go to waste. Remember, it's the person's choice to continue walking towards Jesus or not. Sometimes that path takes turns, falling away, coming back, falling away again, and coming back for good. We absolutely do not know who actually is saved. Someone can look like the greatest Christian out there but their heart could be dark as night and they never actually believed in Jesus.

Now I say all this because music is how God reached me. Many years ago. Was I emotionally caught by the music and lyrics? Yes. Was I perfect after all that? Absolutely not, in fact it took many more years to 'get serious' and even by those standards today I laugh because I am even more different and 'serious' about my faith today. As Christians, we are commanded to constantly try to improve ourselves, but we're not going to get it right all the time. What the devil meant for bad, God means for good. God will turn ashes to beauty.
