It seems for all the nostalgia most listeners like my parents don't really listen to those older songs, and prefer to listen to newer compositions and recordings. I wonder why this is? One of the reasons is fairly obvious, improved recording and listening technology. Another it seems that older listeners enjoy having better access to music that appeals to them. I remember being into the Beatles briefly, and it seems my parents thought they were trivial sell outs. Another fairly obvious observation is that their tastes have changed.
