We sing the Kyrie ("Senor, Ten Piedad") in the Spanish Mass, but we have a custom of rousing songs for closing (Salida).
I'm of two minds on this issue: on one hand, as an ex-Presbyterian (old-school, Church of Scotland) I'm used to a more stately liturgy. On the other hand, the spirit of our parish is evangelical and charismatic, and the Spanish-speaking congregation has little experience of old-fashioned music. Depending on where they come from, they might have seen a priest every five years, or even attended Protestant churches, before coming to the US where Catholic churches are easily available. We have to work *for* the people we're serving, under the guidance of our Bishop and pastor (both solid guys), and try to make everyone's experience of Mass better - where "better" means more productive of holy Catholic lives.
I think that Charismatic Catholics deserve their own rite.
My DH is an Usher and therefore an EMHC. I think in some parishes, the blue haired nuns would be my LAST choice for EMHCs!
