@emergingsoul I listen to about 25% new and the rest oldies. I tend to go by genre or time period. I go on benders where I may listen to soul music from the early 70's or alternative from the 90's. Heavy Metal has also made a surprising comeback and that is usually 70's and 80's. I also listen to a lot of music out of Africa.
In my lifetime there has never been a better time to listen to music I am so lucky that I have great gear to listen, but even if I did not, the amount of music available is incredible.
