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 just use spotDL to download albums directly from spotify/YouTube. I set it to download directly into the jellyfin music folder in a folder with the album name. This way I just paste the album Spotify link on spotDL and it’s done. The album is available with the metadata as soon as jellyfin rescans the folder.
