I don't know about North America or Europe, but in Latin America the Novus Ordo's and the Protestants use the same "music".
The "music" that the Protestants (mainly the "Evangelicals") use in their "cult" gatherings is the same "music" (blasphemous garbage compared to real Church music, actually) that the Novus Ordo uses in the mess and in their "pastoral activities"; they use many of the same charismatic, touchy-feely songs with the exception of the Marian ones which the Protestants of course don't use.
I don't know if the case is that the Protestants came up with these songs and then the Novus Ordo started using them after Vatican II or vice versa. This is something I've always wondered.
The Protestants came up with the tradition, and the Novordiens adopted
the tradition. -- Note: one of the Protestants' protests has always been
the tradition of Catholics, so here they are making up their own tradition
while they continue to complain about Catholic tradition! That's hypocrisy.
The Protestants came up with the songs and then the Novus Ordo started using them after Vatican II.
While this is true in many cases, and is a big topic for concern, it is not
always the problem with whatever music is used at a Novordien setting.
A more general principle is, what music is appropriate for Mass and what
music is not appropriate for Mass. All concerned, the FIRST CRITERION
should be whether a particular piece of music is known to be one used
in Protestant 'worship services' and, if so, it should therefore NOT be used
in the Catholic Mass setting, on that criterion alone, all else notwithstanding.
And the reason is, anyone who is a convert from Protestantism has a
lot of old memories to put away and forget, so he should not have to be
subject to hearing the same music he heard in those heretical sects that
he has abjured.
Some famous hymns sung in Catholic churches were composed by Protestants. The criteria for admission would be the hymn tunes or melody, orthodox texts, and not written specifically against the Catholic Church.
That is ONE of the criteria. But it is not the only one, NOR is it the
most important one. What is MOST IMPORTANT is that any music
that is or has been (especially recently) used in a Protestant worship
service should NOT be used for Catholic Mass. Period! See above.
I have been traumatised many times in the past thanks to Novus Ordo music. In fact, I am reeling in agony right now thinking about it. [Their] music is an affront to Almighty God and his Saints.
Case in point. The music should not scandalize the Faithful. It should
never be a CAUSE of their inability to pray or focus on the Mass. It
should NEVER, NEVER, NEVER be a distraction.
Napoli may have been appalled at the music objectively, on its inherent
merit or lack thereof, but so too are Protestant converts appalled at
having to endure reminders of what they so much desire to leave behind.
What mortalium says is true. I myself went to those horrible, horrible, "masses" in Spanish in the past. Now I go to a diocesan TLM (there are no sspx chapels nearby). I remember there was this one song during the communion where I thought the choir was singing a love song instead of religious song. Anyway, I think most of the songs in those sacrilegious masses are composed by charismatics, not protestants.
FWIW, those "horrible, horrible masses in Spanish" are typical of what
the new Pope Francis has presided over in Argentina for decades. Now,
in liturgical settings where he is expected to sing Gregorian Chant, it
has become clear that he is incapable of doing so. Not only does he
seem to be tone-deaf, but he knows nothing about Gregorian Chant
or what makes it beautiful.
As a matter of reference, the way the Protestant tradition developed
was, Martin Luther imported melodies that were commonly sung in the
pubs and beer gardens of Germany (beer drinking is a serious occupation
in Germany), removed the profane words and substituted Scripture
and other religious- sounding words, and this was very well received
by the heretics at his services. So the tradition grew from there.
Basically, it comes down to this:
When they went to Luther's service, they heard songs that reminded them
of the beer parties they were just at Saturday evening (yesterday) and
then they could spend their time in the religious "worship house" thinking
about their sinful behavior the day before, whatever that was.
This is the OPPOSITE of what Catholic music should be. We go to
Mass not to contemplate our sins, like a dog returning to his vomit,
and thus commit ANOTHER sin of pertinacity - which can become
the sin against the Holy Ghost, the unpardonable sin, but in any case,
it's the sin of attachment to past sins and revelry in them. We don't
do that at Mass, but what we do is to REPENT of our past sins, and
REAFFIRM OUR ABJURATION of error in our past life, which includes
any association we may have had with heresy, among which are
Protestant heresies -- which many of us are reminded of when we
hear songs like AMAZING GRACE, A MIGHTY FORTRESS IS OUR
GOD, BRINGING IN THE SHEAVES, or WE SAT DOWN (by the river
Jordan, etc.).
The point is,
EVEN IF the words of the song are
not even slightly offensive
to pious ears, and if it has direct and obvious ties to Scripture,
it makes
NO DIFFERENCE, when the music melody is reminiscent of a Protestant
or pagan or non-Catholic setting, OR
when the words and the music
together evoke memories of such non-Catholic settings, the music
SHOULD NOT BE USED for Catholic Mass. When a bride selects her music for her wedding, does she
ask them to play "Here comes the bride" for her walk down
the aisle? Maybe she does in the Newage One World Religion,
but not at a Catholic Mass -- why? Because
it's not a pagan
wedding. It is a Catholic wedding, and should evoke only the
Catholic sentiments of what a marriage is all about -- things
like an analogy to the mystical bride of Christ which is Holy
Mother Church.
