In your opinion. Does music (talking about the music not lyrics) appeal to the flesh or the spirit or the soul, or some combination of two or three or ..?
I believe that the recipient determines this. Many a choir dissolve in back-biting while singing nothing but "sacred music". Pride and "self" are enemies that can turn anything sour. Most of the big-name false teachers in teh church use the KJV (like I do), but that does not make the KJV "the bible of the heretic".
You could lock me in a room and play the entire Marilyn Manson catalog repeatedly and I guarantee you I won't come out anything but annoyed... in other words, I, as the recipient would not be affected as others might be.
But you make a valid point... we EACH need to examine our motives for doing WHATEVER we do. Do we listen to whatever music we listen to for reasons of edification or to feed the flesh? It is a good question that sits on Romans 14.
How many CCM-bashers feel superior because the don't listen to it? I dunno, but I bet there are some. Pride and self are insidious and know no genre.
Now, to be honest, I hate the truly hard, loud stuff, because if you can't understand the message then obviously the medium has overtaken the message. This should never happen. A preacher should never be larger than the message (Jn 3:33) and the music should never obscure the clear exclamation of God's counsel.
We ought to! Or at least correct them!
Yes, but we don't throw out
all Pastors.

We ought to chuck out false teachers in CCM too (see: Carman) and correct whomever would be corrected.
The primary use of music in the NT is for the edification of the saints and in the OT it is the song of the redeemed. I think music that calls itself "Christian" can either be used to edify the saints (by reinforcing sound doctrine) or tell the story of redemption (for those who know not salvation).
You'll never find a scripture that deals with "CCM" of course . Nor will you find a scriptural argument that says "Don't smoke crack" (though the two are not in the same group by any means). If you can't find a direct scripture for it you have to look at principles.
Absotively!

We need to look to scriptural principles. I can look to the principle of soberness in regard to the question of crack. I can look to the principle of modesty and the principle of lust=adultery to avoid pornography... As of yet, I have not discovered the "back-beat" principle.
Now, if someone decided never to listen to CCM... they wouldn't be missing much. But I could say the same about a whole lot that is passed off in the name of "Christianity"!
