For me, it depends on the area. I'm from eastern north carolina, Plymouth, NC to be exact. That's near Elizabeth City, Washington, Greenville, that area. IN the eastern part of North Carolina there are lots of small churches without the business mindset. They don't like contracts and if you have one they might not want to abide my it. Also in the Eastern Part of NC, they aren't many COGIC churches. We have a lot of Pentacoastal, Various Baptists and Church Of Christ.
I'm currently in Durham at North Carolina Central University. Therefore in the Raleigh/Durham area I noticed there are a lot of COGIC, holiness and non-denominational churches.
Going back to the original question, I think that it depends on the church and their aspect on the music ministry whether or not if they abide by all of the things involved with the music
