The worst example I can remember was a while ago on the World Service. A contributor was talking about how she loved to be completely alone in a remote part of Greenland. She described how wonderfully quiet it was, with only the sound maybe of the breeze over the ice, gentle waves and an occasional seabird. She had a brought a recording so that listeners could experience it themselves - which the programme makers played AGAINST A TRACK OF 'PRETTY' MUSIC.
