This was a quote from the thread about megachurches and attitudes towards them:
As the pastor of a very small church (and as someone who has visited quite a few small churches recently), I don't know that the issue is necessarily about wanting to "look polished" as much as it is about not having people with enough musical talent or knowledge to do said music in such a way that it won't be more of a distraction from worship than it would be an enhancement to worship.
There is an illustration that people give to describe something that makes them feel uncomfortable. It is that something is like "fingernails on a blackboard." That sound bothers a lot of people. Some people can't stand the sound of the squeaking made by hands on a balloon.
For me, the sound of fingernails on a blackboard really doesn't phase me at all. The sound of squeaking balloons is only slightly worse than that to me. But there is a sound that really makes my skin crawl and sets my teeth on edge--a metal rake against a sidewalk. It often makes my face involuntarily grimace.
There's only one other sound that makes me react in a similar way--including with the facial grimace: it's the sound of sour musical notes.
Personally, I'd rather hear no music than poorly done music in worship services.
