I find the very existence of the "Christian" musical genre to be ridiculous. Genres of music are supposed to be defined by, you know, the music, not the lyrics. Every single other genre is defined by musical qualities--timbre, performance style, etc. "Christian" music is defined by whether the song is about the Christian religion. That is an utterly useless way to classify music (not that genre distinctions on the whole are the most useful things ever, but at least they serve some kind of purpose), and to claim it's your "favorite" or "only" genre is insulting to musicians, because it's suggesting that no matter how good and original and innovative and well-constructed and -performed a song is, it's only worth consideration if it says "Jesus" in the lyrics.
And the existence of "Christian rap" or "country" or whatever is ridiculous, too, because it also elevates genres above all importance--it implies that you don't really care about listening to musically good artists in the rap or country genres (assuming there are any), you merely want to listen to music that fulfills the generic requirements of "rap" or "country," and also says "Jesus." That's rather insulting, no? And it results in every "contemporary Christian" band I've ever heard being content to be utterly unoriginal in every way, merely echoing the broadest tropes of whatever genre they're in, because musical innovation isn't going to be what sells records (not that it is anyway, except in an ideal world, but you know); whether the song has a "good message" will be. This is not only insulting to Christians and musicians, but extremely dangerous; it increases mainstream pop music's artistic stasis at least as much as the latest banal Black Eyed Peas single does, by cynically casting aside considerations of quality or innovation and asking listeners to like something just because it mentions God.
Anyway, here's final proof that music's being "Christian" or not has no bearing on musical quality:
"Christian" music: Bach's Mass in B minor, "Jesus, Take the Wheel"
"Secular" music: Winterreise, "Boom Boom Pow"
"We are symbols and inhabit symbols; workmen, work, and tools, words and things, birth and death, all are emblems; but we sympathize with the symbols, and being infatuated with the economical uses of things, we do not know that they are thoughts." - Emerson, "The Poet" (Essays, Second Series)
