Some rock music is really demonic, God hating and even the medium is part of the message. But I have friends who are godly people who write and play rock music. It doesn't really do anything for me, but I have to be careful.

I think it gets down to the reason and motivation in the music, but some of the modern music is such rubbish musically its hard to believe that God would want to use it. Then again, God has worked with all kinds of inferior things over the years, so who I am to say.
