I do not know, simply because I do not kniw what you mean by a "rock beat". The percussion would be more "rock" than traditional hymns, but I would not compare it to rock. But then again, I have never experienced rock in a contemporary worship music service.
I doubt very seriously that you would like biblical worship music either (their stringed instruments, drums, halil (that flute linking thingy), and the chant type singing. I would not like it, as it is too foreign to me.
But that does not mean God does not like it. Obviously He does as He told them to praise Him with those instruments and that type of chanting.
Now, if you are saying that Contemporary Worship Music is unacceptable to the Holy Spirit then there are serious warnings you may need to consider. But again, I do not know that we are talking about the same thing.
Here is an example of what I am talking about (as there is a difference between Christian Rock and Contemporary Worship Music):
I am interested why you believe God rejects that worship when sung in praise by a congregation yet would accept Western hymns foreign to the music of the Bible.
