John Paul II wrote, “Today, as yesterday, musicians, composers, liturgical chapel cantors, church organists and instrumentalists must feel the necessity of serious and rigorous professional training. They should be especially conscious of the fact that each of their creations or interpretations cannot escape the requirement of being a work that is inspired, appropriate and attentive to aesthetic dignity, transformed into a prayer of worship when, in the course of the liturgy, it expresses the mystery of faith in sound.”

Another reason to like that Pope.
