[livius]

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.

[TotusTuus]

Yes, the liturgical action should be authentic whereby those present bring forth the best of themselves (and the material around them) to respond to God in the sacred dialogue with Him in union with all the angels and saints.

Hence the use of living flames for candles (no electric stuff), real bells, incense, etc.

CD's are good in their proper place. The sacred liturgy is not the proper place. The prayers (music if sung) should come authentically from those present.

An orthodox bishop told a friend of mine that according to Canon Law, the only recorded music that can be "played" in church is Gregorian chant. I got to hear the monks of Santo Domingo de Silos chanting in a church in NJ. It was quite conducive to prayer at the appropriate volume, not to mention it was very beautiful.
