I think the atmosphere of the congregation tends to dictate what is sung by choirs or praise teams. Now, while
we may not like it or agree, it is what it is.
While I was MOM (at a particular Baptist church) there were a
LOT of songs that I couldn't introduce because I
KNEW the congregation would sit there with this face------->
or this one----->
Every once in a while, I'd be able to get one or two in: Kirk Franklin's, "Don't Cry" went over
BIG one Easter (this from a congregation that
HATED Kirk Franklin
).
Anyway, I think the music ministry has to reach the congregation where they are, then try to slowly implement new, fresh music to stretch the boundaries without upsetting the church as a whole.
Great question, BTW.
