Ok, heres a small chunk out of The Purpose Driven Life by Rick Warren...."Worship has nothing to do with the style or volume or speed of a song. God loves all kinds of music because He invented it all--fast and slow, loud and soft, old and new. You probably dont like it all, but God does! If it is offered to God in spirit and truth, it is an act of worship." Isnt that rad, that means God loves Metal!!! Given its played for him, but still, thats rad.
