I’ve been maintaining a self-hosted music library for so long (30+ years now), there used to not be any tools for editing metadata. I used to have to go into file properties and manually edit the data for each individual MP3 file. Nowadays, I use Mp3tag to manually edit entire albums at a time. I have ADHD though (the hyperfixation kind), so I’ve literally dedicated thousands of hours to manually fixing metadata.

I guess I never bothered to look for more advanced tools to auto-update metadata. I had to go in and manually fix stuff that updated automatically from the Internet in the past, so I guess I stopped trusting online databases. But they’ve really advanced since the last time I went searching for tools, and their databases are a lot more complete in this day and age. I’m gonna play around with some of these programs and see how well they work.

I host my music library through Plex, then use Symfonium on my phone if I want to stream my Plex music remotely, just because I like their interface a little better than Plex’s.

I’m interested to see what others are doing here. All I do is update tags with MusicBrains before dropping them on my NAS for Plex & Jellyfin.

I may not understand your question, but I use Jellyfin as the backend for my music collection. It draws metadata from MusicBrainz and passes my listen stats to ListenBrainz. I believe that those plugins are in Jellyfin’s default repository.

Right now I’m bouncing between OSs, but on Windows my CD ripper (EAC) draws metadata from MusicBrainz as well. On Linux I’ve been using K3B as a ripper which still works (nearly 20 years after I first discovered it!), but oddly for KDE software, is not as configurable as I would like. I believe it also draws metadata from MusicBrainz.
