I'm in the choir of my ECUSA parish (bass-baritone). I'm pretty good at sight-reading. I went to my wife's uncle's funeral, as a pall-bearer, at a local Catholic parish. When the first hymn came up, I opened up the hymnal (noting that it was in unison; the 4 parts weren't written in) and started to sing. Just about everyone else there was Catholic.
The first thing I noted was that I was the only one singing. The second thing I noted was that there was a good reason for that; the hymn was just about unsingable unless you, like the church musician, didn't mind sounding like a hotel lounge singer. I tried joining in on the second hymn and gave it up as a bad job.
My wife interrupted me in the car as we left; "I know, the music is terrible." I told her, "Put a baseball bat in my coffin. If the musician starts playing 'Wind Beneath My Wings' as my coffin is wheeled down the aisle, I want you to grab it and whack him with it until he stops."
Say what you will about the ECUSA, but the music is a lot more amenable to a spiritual approach to God than what I heard that day.
You may have been in a Catholic church, but what you heard was NOT Catholic music.
I rarely hear Catholic music in my Catholic parish.
