When I'm busy doing something else, like cooking dinner or reading the newspaper or even chatting with friends, it's nice to have music playing in the background. There are, however, certain types of music that don't work for this purpose, for example the piano concertos of Rachmaninoff. I have to listen to his music with concentration and single-focused intensity To play Rachmaninoff in the background as ambience seems disrespectful. I feel the same way about photography.
