I have a folder of MP3s, some of which date back to 1999, just a few years after the format was popularised. Most of them have utterly terrible names (think RIDEONAM.MP3). I think at this point they might even survive the heat death of the universe. And they’ll still be terribly-organised.
I’ve been using Tempo with Navidrome and it’s really good!
+1 for Feishin if you want a desktop client as well.
