I guess I missed it.
The Changes here I can mostly understand, don't necessarily like them making them, but don't see too large of a problem. Since the majority of the changes are for song instead of chant, I can live with that. Let's be honest, we weren't going to see the return to Gregorian Chant every Mass. As for a few others, small, as long as the majority of the changes remained, David Haas and Marty Hautgen's Mass Parts are history.
