Then: Vibrant creativity and authentic analog sound of the 60s-early 80s, all music was recorded with real instruments
Now: Availability and ease of use provided by computers/free software/internet meaning more music being made than ever before, plus algorithmic sorting providing exposure to only the best of the best the world has to offer.
