CCM's purpose IS to provide an alternative to mainstream entertainment. I really am astonished that you find that "foolish and arrogant." What would be the point (for a Christian) of tuning into the local pop station and hearing Zoegirl, Plus One, Avalon, Christina Aquilera, Avril Lavigne and Lil' Kim all mixed in together? How does that provide an alternative for someone who doesn't want to hear all the filth in most mainstream music today? That would be like PAX TV running Elimidate, Howard Stern, South Park & the Man Show. For non-Christians on the other hand, it is a good way to plant a seed. For example, in the early 90's when Amy Grant and Michael W Smith had a few mainstream hits, I'm sure there were people who bought their CD's that normally wouldn't, and were exposed to more overt Christian themes on the rest of the album.
I don't know who your favorite bands are, but if you're as dead set on originality as some of the other posters, it's likely that the bands you like don't compete all that well amongst other bands in the mainstream. They may have a decent sized fan base, but they aren't making the kind of jack the record companies would like.
Anyway, we've now come to a place where you've all but admitted that you don't know what you're talking about. You shouldn't have trouble coming up with bad theology in CCM, if it's filled with it, even if you don't listen to it normally. I'm not saying that is the case, you are one of the few who have been able to speak from the experience of actually having been to some CCM concerts.
I like ps139 am ready to get down to business. By the way, the lyrics you find should have some theological message. We've already discussed Relient K, and there will obviously be some songs by other artists that have NO message at all. Loophole closed.
