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 don’t really do the folder of MP3s thing any more.
I am much more into the Jellyfin full of FLACs thing these days!
I bet up in the attic next to one of my sweet old Abit motherboards I have a dusty old hard drive with a folder full of music from the 90s and early 2000s.
