One of our (meaning Catholics across the board) overarching problems with Liturgical music is that it is in competition with the celebrants at the altar and in the sanctuary.  Catholic Eucharistic liturgies have not gotten even close to the true concept of community celebration.  That's what the black Protestant churches - and the black Catholic churches by extension - have had down pat for a very long time.  The form of music is secondary to the fit between it and the confection of the Eucharist.  It has been - historically - a competition between the two.  A wonderful liturgist I know told me not so long ago that it will always be so due to the nature of our particular form of worship that is rigidly set in one and only one way.  Describes the whole Church, doesn't it?  He went on to tell me of how many Church choir directors have intense competitions for who can produce the most thrilling music.  One need only attend Mass at various NYC major churches to know how true that is.
