I do want to also point out that one of the biggest problems among Christian music artists is the fact that a lot of people don't know who they are. In some ways, the CCM industry seems like a "pretend" music industry while the real musicians are out there in the mainstream or secular industry. I hinted at this before, but even the "well known" artists are comparatively unknown. Makes me wonder how these guys and gals make a living! I understand the whole "it's about Jesus" thing, but at the same time, if you are going to make a living in music you simply must sell something. And people wont buy it unless they want it. You don't go on tour by faith alone - you need some cold hard $$$. Even in the general music market (or the arts in general), it's not a super lucrative profession and with the advancement in technology (including our good old friend YouTube), it's easy to listen to music without having to purchase it.
Being that the Christian music market is a very small "ghetto" if you will, I (yes I'm saying this) wouldn't recommend that someone with aspirations to be a professional musician to go into Christian music (at least not initially) OR unless the Lord God himself has given you a specific calling. But besides that, the industry itself is just that. It's an industry, a business, and the machine is not really concerned about how "Christian" the product necessarily is - just as long as there is a positive cash flow. Interestingly, I think that gospel music fares a little better because it has strong roots in the church. Even people who don't go to church or profess to be Christians can somehow relate to gospel music if for no other reason than "it's a black thing".
