In churches of every country of the world Christians sing. And good or bad music makes a huge difference to a service. It can be a powerful attraction for outsiders. It can also drive people to distraction.
More people seem to be put off church going by unacceptable music than for any other reason.
C.S.Lewis hated hymn singing. He found the poetry unbearable, the theology faulty, and the music distracting. Rather than quit church going, he survived by attending a simple Anglican communion service with no music. He also wanted the Book of Common Prayer exactly as written with nothing changed. But many others want the traditional service of their denomination interspersed with three or four familiar hymns.
