I have just watched a TV recording of a programme about the new steam locomotive Tornado trying to reach 100mph. Instead of hearing the wonderful sounds that the attempt must have created we were 'treated' to a crescendo of maddening muzak. Why do producers insist on wrecking otherwise entertaining programmes with this type of irritating and superfluous racket? Complaints usually receive a standard reply (if any) that it 'enhances' viewers' experience. Really?
