I wonder about that in the modern age though. I mean there has to be a factor of how easy it is to copy and store. So likely a lot was lost before performance recording capability. In the car I mostly listen to npr but when I don’t care for whats on I will just sorta jump between stations and there is a thing now for stations to kinda take a time period but they don’t seem to be very discriminatory about it. On the other hand now that we can call up any song we want likely you will see the cream come up to the top on what gets asked for a lot. I have one particular gripe though because my fav band tull had this album crafting they did where the position of songs, especially the first and last, were real important. They have these special editions they kinda just tacked songs on them and it ruins the flow. Its impossible, at least with amazon, to get the device to do the original vs the special edition that it defaults to.
