Music is inherently good, friends. It's only bad when someone uses it for the wrong purpose. Consider it: as human beings, we did not invent the idea of music: God created us with it. When people make music and don't misuse it by merely attempting to garner attention or speak evil, it glorifies God, who created music. I've heard good secular music (that is, it doesn't contradict the truth and demonstrates appreciation for the aesthetic value of music) and I've heard bad 'Christian' music (music with lyrics showing an unchristlike attitude, and a laziness about aesthetic). Artists are either Christian or non-christian - music is not. Also, we need to keep the distinction clear that even though Christians making music should glorify God this does not imply that all music they make should be self-consciously designed for corporate worship. I think polka music has a fun and infectious joy to it, but I would never dream of using it in corporate worship even though I might love to hear it played live at a festival. Some music is set apart as coporate worship music. Just because some music is not designed for that purpose does not make it satanic, and it doesn't even mean it isn't glorifying to God. Perhaps the real question is : if my brother makes music, do I have a right to attribute it to the devil? Unless we are saying that Satan literally dwells within music instruments or within the soundwaves themselves (which sound fairly ridiculous not to mention lacking biblical proof) calling 'Christian' rock satanic is tantamount to saying my Christian brother is posessed by evil spirits. And it isn't possible for a christian to be possessed.
