Father Edward McNamara, professor of liturgy at the Regina Apostolorum Pontifical Athenaeum, deals with the issue of attaching a particular theme to a Mass in this article, entitled "Polka Masses", supposing that would attract those who feel drawn to that theme.
Perhaps the principal difficulty with such things is not so much the music in itself, which like many human elements in the liturgy may have different meanings in different cultures and in different epochs, but the idea that the Mass needs some sort of a theme in order to enhance its significance or relevance. When we label the Mass we tend to diminish rather than augment its importance. We restrict its universal meaning as Christ's very sacrifice renewed upon the altar and the sacred banquet which forms and increases our union as part of Christ's Mystical Body, the Church. This is the Church's greatest offering to God and any addition to the Mass itself -- such as "Polka," "Clown," "Disco" (yes, there have been cases) or any similar extraneous element -- reduces its scope and attempts to press it into service for some cause other than the worship of God. It could be argued that this is done in order to make the Mass more attractive or welcoming to certain groups. I am certain that it is often done in good faith. Yet, I think that 40 years after the Second Vatican Council it is clear that such attempts have failed to fulfill their promises. The best and most efficacious means of making the Mass meaningful is to teach Catholic truth as to what the Mass is.This is, without a doubt, the most concise expression I have read on how the modern mentality toward the Mass has reduced it to a strictly human work. They think it is just another form of entertainment to be sculpted at will. Rather, we ought to take our cue from the Book of Revelation as to how the Eternal Liturgy is celebrated in heaven, of which the earthly Liturgy is supposed to be visible manifestation.
