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.
You’ll find that MusicBrainz Picard is a heaven sent tool to properly tag your files, with optional proper renaming.
It takes some getting used to, and I find it works best in whole albums, but produces a much more professional library.
mp3tag (mp3tag.de) is great too.
Picard sometimes falls short on cover arts and track names of some niche or non-english albums because of that mp3tag with discogs is sometimes needed
For Linux there’s puddletag, which is very similar to mp3tag
puddletag was actually based off mp3tag, but even has stuff mp3tag doesn’t have. highly recommend.
Oh I’ve been looking for something like this for a long time. I wonder how this integrates into something like Jellyfin if I want to host my own personal music streaming for myself.
In addition to autorenaming Picard can also auto organize into folders. So any time I buy new music, I run it through Picard to ensure metadata is correct, grab lyrics, and put it in the right folder that is then picked up by my self hosted navidrome
Picard is literally the only Jellyfin related tool I use that isn’t fully automated, because somehow the automated versions I could find were doing things like renaming files on a 60% confidence of the filename and I had to nuke and re download my library.
So instead I open Picard, click 6 whole buttons, and my entire library/new files are renamed, tagged, and sorted 100% accurately.
I use Jellyfin also.
My workflow is like this: buy CDs from Discogs, rip them to FLAC, adjust filenames, covers and metadata with Picard, push the files to Jellyfin that promptly detects the new files.
I also use Soundconverter in Linux to generate MP3s files for devices that don’t support FLAC.
I’m very happy with this setup and my collection has never been so organized.
