Where jazz has its standards, it feels that the (post)modern standards are songs we have ingrained in our memory to a point where we apprehend every bend and squeal, even if it is not performed.
It is interesting to think of these songs in association with algorithms and the choice of what is played and performed. Has nostalgia replaced originality or is all music copied as people like Chilly Gonzales demonstrate.
Here I am again reminded of a comment from William Gibson:
I have no idea what era of music we're even in, now. Do we still *do* that, eras of music?
