Ok. So you've got me stuck between a rock and a hard place. Yes, I posted that sometime back. Let my explain my position and also say that I don't expect anyone else here to be convinced by it. But here it is--
I do believe that I am required to conduct myself according to the Word of God in every area of life. This includes how I worship, what I wear and what I listen to. That is my main operating principle.
In carefully searching the scripture, I do find that it has a lot to say by way of application about what I may listen to. I am to avoid "filthy communication." I am not to delight myself in things that glorify and extoll sinful behavior. I am to think on things that are good, wholesome, beautiful. Others may disagree with me here, but I do not see that only "Christian" art (include music here) may be enjoyed-- but at the same time, the other parameters still apply. Finding "rock" music that does not glorify sinful conduct is quite a challenge, and quite honestly, my record collection is indeed very slim. But what I do have, I do enjoy, but never want to use my liberty as an opprtunity for another to stumble. And as always, I strive to be humble and teachable-- always ready to lay it aside as soon as I am convicted by another brother or by the Holy Spirit by the means of the scripture that it does indeed bring a reproach upon Christ by disobedience to His Word. IOW, I hold it very lightly.
Now in applying my music tastes to the worship of God-- I simply don't. God regulates His worship by His Word, and nothing that He has not permitted is to be permitted in corporate worship. Singing in worship is to consist of "psalms, hymns and spiritual songs," sung corporately (not by a performer or by performers) in a way suited to worshiping the eternal King of Kings. Simply put the music of the world has no place in the corporate worship of God.
