One thing about this survey that needs be reminded, most Catholics live now with the utter absence of traditional liturgical music such as Gregorian chant, and have for well over 40 years now, so how would the majority ever be able to think of this when answering such a survey?
One thing that is interesting though is this statement:
"Currently filling in as a parish choir director, McMahon said, "I'm always surprised how many young people ask for 'Ave Maria' or 'Panis Angelicus' at weddings and funerals."
Again seemingly pointing to the interest, if not in many cases the outright thirst, for more traditional forms amongst the young. I can't say that I know too many young Catholics interested in "On Eagle's Wings".
At any rate, let's always remember as well that mere popularity is not the criteria for liturgical music. Its also about its formative power and appropriate character as regards the sacred liturgy, and not simply one's emotional attachment.
