INFLUENCE OF RELIGION IN MUSIC

Here in our little country, BELGIUM, we have 1 main religion: CHRISTIAN --> CATHOLIC. In the "horrible" inquisition time, a lot where emigrating. Also there were a lot of people from the "FLANDRES" (Belgium is in fact ARTIFICIAL) who went up North to the NETHERLANDS.
In fact the Flanders started in France, Belgium and the Netherlands. Problem, every year there was a war somewhere, and the English Island was covered on the East Side by the Netherlands, at that time one of the most important countries.
Probably too important, and also around mid 16th century there was the spread of Protestantism - particularly in the cities. So people moved up NORTH or went to the New world AMERICA. New York was dutch at the beginning.
But when did the "typical American phenomenon started"? All these different religions, while here religion is going backwards the USA is one of the most religious countries.
51.3% of Americans are Protestants, 23.9% are Catholics, and 1.7% are Mormons.
What about the BAPTISTS, METHODISTS, LUTHERANS, PRESBYTERIANS, THE DISCIPLES OF CHRIST and a lot more.
If you go to church and you are a musician what KIND OF MUSIC IS PLAYED? Is this the same in all these different churches?
The Afro Americans and gospel, I was overwhelmed when I went to church in the south, to see, hear that fantastic "spectacle" So in fact I read a lot of topics about music played in church.
- 1) WHAT KIND OF MUSIC is played, BOB DYLAN, JEFF BUCKLEY? or completely different music.
- 2) WHAT KIND OF MUSIC is played in the Afro American churches, are you allowed to play blues? - 3) IS MUSIC ALLOWED IN EVERY CHURCH?
I would love to have answers, because here in our country going to church has dropped a lot.
In 1967 : 42,9% went every week to church, in 1998 only 11,3%  HOW IS THE SITUATION IN OTHER COUNTRIES.
