Although, I agree that there can be commercial abuse in any billion dollar industry, I think it unfair to lump all of any category of music all together as evil or to be avoided. Let alone 2 categories. Yes, we must be careful in all areas where the world has gotten a finger into the pie, but that in no way takes away from the fact that there is some awesome, worshipful music to glorify God that may be considered rock music to some, and certainly CCM.

I believe that part of our job as Christians to to take back territory for the Lord and if you look at the history, what is commonly known as 'rock&roll' actually originated in the southern Baptist church and was used entirely to praise God. It was the enemy who stole it from God in the first place so it is part of the calling of end-time Christians to make full use of this powerful, moving tool, to take it back and glorify God with its full, proper use.

Peace of One,
John 17-21

Examples of God's use of music in the bible is extensive, but perhaps my favorite use was in 1Sam16 where it is said that David's playing cast evil spirits out of King Saul.
