Musical variety enables us to hear the same words with different effect. "Amazing Grace" has a different emotional impact when it's accompanied by a black gospel choir, a large orchestra, a sustained synthesizer chord, or a lone acoustic guitar. Hymns are especially suited for innovative treatments that help us hear the words from a new perspective. Moving beyond traditional tunes and arrangements shouldn't bother us too much since most hymns were written without music, and a favorite tune only emerged over time.
