Music was created to glorify the Lord... music that glorifies things other than the Lord or at least is in agreement with the Lord... is inspired of the devil. Pretty simple.
Here's what the Lord said about it thru the Apostle James...
James 4:4
You adulterous people, don’t you know that friendship with the world means enmity against God? Therefore, anyone who chooses to be a friend of the world becomes an enemy of God.
I was just thinking since the topic said Christian Music Forum that... maybe Christians would be posting Christian music. Apparently not.
There was lots of good old Christian music in the 70s... I don't know much about the 60s Christian music scene myself.
