I wish the church would use Bach for the time the congregation is entering and leaving, even if the music is on CD.Its nice for a background for personal prayer. These days too many people are socializing during the pre-mass. They know where their friends are. The can converse after service.
Oop! I think I just double posted.
They're not supposed to use recorded music, but they can play anything they want for the prelude (before the entrance) and the recessional after Mass. Some churches do a fairly long set of prelude pieces, and this actually does keep the chit-chat down.
