Music, art, dance and every other creative expression have one great purpose: to honor and glorify Almighty God and to bring the truths His Church teaches us to light.
The problem with 'christian' (so-called) rock music or any other populist attempt at relevancy, is that most of these 'artists' are striving for the LOWEST common denominator. That's why today, we have the joyous strains of 'christian rap', which is, for the uninitiated, made up of the dulcet tones of someone saying rhyming words, usually in an idiotic pidgin language that barely resembles English, over a repetitive and animal drum beat or other loop of noise.
I have been playing guitar for 25 years now, and I can play the vast majority of 'christian rock' after hearing it once, because it is usually kindergarten-simple. The lyrics often reflect the banal and, again, intentionally populist bent of the composer.
Art, as they say, imitates life in many ways. It tells of our desires, devotions, biases, loves, hates and goals. With that said, our spiritual lives very often reflect the diet of art, music and other creative expressions we fill ourselves with.
In short, if we were to truly plumb the depths and scale the heights of GREAT music, we would realize VERY quickly that "Lord, I lift your name on high' and all the other prot-rot lyrics are no suitable match at all for the wonder and awe that truly Christian music inspires in us. Likewise, "O Salutaris Hostia" cannot be wedded to "sturm und drang" rock music; it is simply too lofty and sublime an expression of truth and adoration to be paired with two-finger grade-school guitar chords.
St. Cecilia, lover of music and worshiper of Our Lord Jesus Christ, pray for us.
Mary, Help of Christians, pray for us.
Most Sacred Heart of Jesus, have mercy on us.
