He brings up an interesting point.
Sometimes church "worship" services can get a little out of hand with their music. By this I mean that they concentrate solely on the talent of the person singing and not on God. Worship is about God, not puffing up a performers pride.
Also, it says in the Bible that Satan was in charge of music in Heaven efoe he was kicked out. Pretty interesting eh?
I also believe that Satan absolutely loves alot of today's music. Just turn on MTV and you'll see what I mean. True talent and soul in music isn't as important as big boobs anymore. It's petty sad, but I believe Satan's happy with the music industry. Heck, look at all the musicians who die from drug overdoses. Clearly alot of people in the business are messed up.
That said, it doesn't make music evil in any way. Just like anything, you can use it for good or bad. I think that guy is definitely taking things too far.
