Yes, the singing. They never stop in this church. A bunch of guitar and tambourine playing hippies singing all through the mass, including over the consecration of the Eucharist. Drives me nuts, I didn't come to a concert, I came to mass.
I went to a conservative church when I was a kid. Some of the priests still did the odd latin bit and until the 1980s you still had to kneel to get communion. The music was part of the mass, of course, but it never was in competition with the liturgy. And they didn't make us sing every response, which in my experience just results in about 85% of the church standing there and not participating. Would that I could find such a church today.
I noticed that intrusive singing last Sunday. Wierd, I used to really love the music part
