I am arguing for more effective Christian music. You say "Sometimes they are successful and sometimes not." This seems to be a relatively cavalier attitude when it comes to souls. I am in no way bearing witness to anyone, but I'd think that the whole point is not to express yourself (which sucks 99.99999% of the time) but to reach hearts and minds with the message. To quote jack black, "I can zippity doo dah you a song, but it would be false."
You obviously "like" these christian acts and will accept them warts and all because you like the message and aren't critically looking at the execution. You hear a song and like it and that's good enough. Well, I listened to it and don't like it, but I will go one step further by trying to examine why it's crap with the hope that someday, a Christian musician will work for his audience and package his sacred message in a manner that is essentially the industry standard of mass media.
