One thing to note about christian music, is that its designed to be non threatening for suburban mothers. the musicians might be great, but they are very specifically trying to not "play in the way of God" or whatever. Thats why its all milquetoast in tone, they very much arent allowed to shred or do anything that might be interpreted as showing off in front of god. Honestly i think a greater act of worship would be practicing and playing the greatest damn classical shred riff you could muster, but if I spent time complaining about logic I would never leave the internet.
