It is quite good.
One question:
How is a congregation supposed to sing along?
A congregation is not supposed to sing along with a polyphonic piece performed by a trained choir. The notion that the congregation is supposed to sing everything is a modern innovation and has never been mandated in the rubrics. Just sit and listen, and get used to the idea. It is a disgrace that modern US parishes with 5000 families of record do not even have a serious adult choir.
I hate to use the example of a heretical displacement, but the Anglicans solved this long ago by allowing the most beautiful singing by the choir at many parts of the service while the congregation gets vigorously to sing from a huge repertory of strong hymns at various points. Purely aesthetically, and speaking as a church musician, they are the one true church. However, this would not work in the Roman Catholic Church, because our hymnody is ghastly and the ability of our choirs to carry on their part of the load practically non-existent.
The only real solution for the RC church is what they have practically done in Rome, with those ceremonies you see from St. Peter’s. It is not an ideal performance of the chant, but it is not absolutely awful, and it does allow everybody who can follow the music to sing along. Supplementation with polyphony would be very nice, but as I just pointed out, they now don’t even do that at St. Peter’s in Rome.
The person who posted that this stuff is easy knows little of what he speaks. Polyphony is extremely demanding and requires the most intense professional preparation and rehearsal. The Gregorian chant, in its original unaccompanied form, is an extremely complex repertoire that was originally delegated to specialized scholae in post-Carolingian Europe, at monasteries where a few talented men could figure out what at that time was a mind-bogglingly complex set of chants. Even today, at Solesmes, those recordings you hear are made only by a handful of monks, and the day-to-day liturgy is accompanied on the organ.
