I don't dispute that there are objective standards. I just think it's important to admit that they are human standards, not divine. And I also don't dispute that everything we do in liturgy should be done well and with intentionality. God certainly deserves our "first fruits."

I only take issue with the presumption that some musical styles are more intrinsically pleasing to God when, to the best of my knowledge, God has never revealed that information.

Conversations like this bring to mind the old saying about funerals being for the living. I think the same principle can be applied to liturgy. We come together to worship God, but the styles and forms involved in how we do it are really about human tastes. God's glory isn't diminished by poor liturgy any more than it's enhanced by great liturgy. The loss or gain is all on our part.
