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 use Symfonium and an easily happy with it, if it helps. Not foss - you have a one time fee (aka buying - not a subscription), however. I found it worth it, and use it in conjunction with a Navidrome instance.
I’ve been using Tempo with Navidrome and it’s really good!
+1 for Feishin if you want a desktop client as well.
