I'm the OP, and I'm surprised to find this article on HN at all, let alone the front page!
Many comments are focusing on music but the thing I tried to get across in the article was that good radio wasn't primarily about the music, it was about fun and connection. A good DJ kept you from just turning the radio off when you heard that same hit the fourth time today -- you wanted to keep listening because the DJ made it fun. It made homework and hobbies feel a lot less lonely. A Spotify playlist sure as heck can't do that.
