Nostalgia has a strange way of making everything look prettier.  For instance the music played on the UK 1940s Radio Station music and vintage radio shows from the 1920s 1930s 1940s seems to me to be more good than bad.  However, the music played on current pop rock stations seems to me to be more bad than good.  I wonder if, 50 years and four generations from now, the music of today will also have the same type of soothing, safe, perfect in the background appeal to future listeners.
