adstrinity:
I REALLY don’t like those clappy snappy songs, either.

I remember talking online to a kid (21 or so at the time) who hated this as well!! They do not belong at Mass. That is NOT what Mass is about. One is taking the focus point off of God at Mass with these songs.
There were several other posts to this effect (so adstrinity you are in good company!) but I just chose the one as an example. I agree that nothing should be sung that teaches anti-Catholic theology through the song, & also that being theologically sound does not make it a good song. It is not an easy job to be a GOOD music director.
Nonetheless, I do not understand this animosity for excitement in the Catholic church. While solemnity does have a proper place, why can we not sing out in triumphant joy to praise the Lord as well? How is that not proper for Mass? The psalms are full of examples that were sung with (then) modern instruments in accompainment & shouts of joy & praise were common. As were people who shouted out in lament. Days of atonement. Days of solemnity.
It seems that here in the US, we’ve gone so far outside the norm (I mean by this that we have emphasized the feel-good, all-inclusive, joy & praise to the detriment of the rest) that there is a backlash of sorts. People are now going back to the Tridentine masses. Nostalgia does get its fair share of publicity, but what I hear most commonly as to why people are staying is the orthodoxy of the parish. The music exemplifies the orthodoxy, in a sense. People find the “traditional” songs a welcome relief as it is a clear indicator of our “traditional” faith being present.
I was a CORE member of a Life Teen youth group a few years back. For any who don’t know:
Life Teen is a youth group program started in AZ. It follows the same structure of the mass: gather, proclaim, break, & send & always starts with the mass. What is most interesting is that the AZ mass is attended by thousands of youth & from what I gather led by a very orthodox (albeit motorcycle driving) priest. The youth are drawn in through the popular music, the ability to clap (not for each other, but as an outward expression of their inner joy), etc. But they stay because of the truth. They had a petition presented to the priest with thousands of signatures asking him to extend his homily; I believe it is now 2 hours long. Then after mass they go to the Life Night, which is themed around a Catholic topic. They stress adoration, confession, & all other tenets of our faith. This music is an honest instrument of proclaiming the truth to those who would not have listened otherwise. To make a sweeping generalization that it inherently does not belong at mass is, I believe, rather short-sighted. What most people don’t want is the liberal theology that often accompanies it. (Although I do allow for personal taste as well.)
I go back & forth between my parish’s Life Teen mass and “regular” full choir and organ mass. We also have folk masses of various types, speaking only, & other such that I don’t like (but many others do). None of these are inherently wrong. They speak to different people, all at different stages. All keep the focus on our faith, but just emphasize different parts of it. The reason I prefer the Life Teen mass (even though I don’t like the cantor’s singing) is that I can encourage my daughter to show joy during the Mass, & I take the opportunity to explain why we are joyful. I can sway my hips to the music and keep her attentive. She knows all the prayers & songs through her active participation. She can move around at certain times. But she also knows that there are some times, even at a Life Teen mass, which are not OK to move around (like the consecration and through communion and the homily.) She understands that no matter what type of music is playing, what type of mass we attend, these same things always occur and always demand attention & respect. I’ve taken her to mass with me since day 1, fully regretting the 1 time I put her in the nursery & even more so regretting the time I used the cry room. While she can sit through a “normal” mass just fine, I find that all involved have a more sacred time during a Life Teen mass. It speaks to her & takes her current stage of life into account. I see nothing wrong with that. (So long as the message is orthodox, which I understand many people do have a problem w/ at their particular parishes.)
A perfect example is the comparing & contrasting of Pope John Paul II and Pope Benedict XVI during WYD. While JP II was likely to swing along with the music & show other outward signs of joy, Benedict prefers to not bring attention to himself, instead focusing on the message at hand. There are several news articles floating around about this exact topic. Neither approach is wrong, & both have a strong tradition within the church.
