@Adrian ada,
Every kind of modern music, without exception, has been condemned when it first appeared. Ragtime, jazz, blues, rock-'n'-roll, punk, rap, hip-hop, funk, you name it.
But that's not the way I see it. To me, music and poetry live in the same field. Both, done and done well, intensify emotion. I recently described poetry as "emotion honed in words"; music, on the same wavelength, is emotion honed in sound. This sharpened, honed, intensified emotion effects us and we in turn must come to terms with it. When I'm angry and melancholic, I listen to heavy metal a lot because it calms me down: it helps me confront the extremes of my emotion and in the confrontation helps eliminate it.
The best music and the best poetry both help you strengthen emotions you wish to strengthen and deflate emotions you wish to deflate. It is a tool for aiding our sanity--and thus it is not evil.
My point for introducing poetry is also to say: those who devalue music must necessarily devalue poetry (music is the sonic realization and poetry the verbal realization of the same basic instinct, namely, the desire to convey emotion). Since vast portions of the Bible
are poetry, the devaluation of music leads inexorably to the devaluation of poetry leads inexorably to the devaluation of the Bible: saying music is evil is evil.
