Some people go to commune with their fellow man.
Some go because it makes them feel good. It's odd, given our vast archives of sacred music, but I never encounter anyone who goes to Mass to hear the music, even though Sunday after Sunday for the lion's share of the time during Mass we have the singers performing, not the priest praying. As someone who goes to Mass to communicate with God, I, for one, find these performances annoyingly intrusive. I would love to have been a fly on the wall when the powers responsible for this deplorable state of affairs were deciding what the musical future of Catholicism would sound like. It seems obvious that these people had little or no creative talent.
