You're talking about entire systems. That's something to be optimistic about too. But it's actually not the thing the comment you responded to was about. I'm not saying I'm excited to get out of the Apple Music ecosystem (I like Apple Music, the service, quite a lot). I'm excited to get out of
Music.app, and into my own custom Apple Music player; one where playlists and play history are simple, sanely-schemaed sqlite databases.
I gotta be careful, I'm going to talk myself into staying up late tonight building that.
