I don't get the impression that things have changed all that much in Catholic music publishing since this FEL Publications case. It sounds very familiar. There are still major music publishers that require parishes to destroy all books at the end of the year. Its the old story of "you don't have ownership, you have a license." This grift predates the "purchasing" digital videos on Prime and the like.

If anything there are even more requirements now. Churches must now purchase individual licenses for music sung in live-streamed liturgies or printed out in programs (through websites like www.onelicense.net).

Thankfully, liturgical music is a pretty old genre (the oldest still around), so there is a huge corpus of public-domain works.
