Navidrome works best with a library that is already well-organized, but it can do some things in terms of library management, particularly with the use if plugins.

There are some good tools for organizing your library, such as beets, Picard, etc. I did not have good luck with beets because I find it a bit complex for a CLI tool, and a lot of my library is composed of singles and mixes. It seems to do better with whole albums. I use Strawberry player for local library management, which has tools like Picard built in, and also connects to lots of things like lastfm if you want. You can also add lyrics with a tool like lrcget.

If you have existing playlist files saved, Navidrome will automatically import them. It can also make new playlists, and there are plugins for smart playlists, etc. Once you set up Navadrome, you shouldn’t have to touch it very much because it will automatically monitor and update your library if you set it up correctly, which is not difficult at all It’s a little bit more specialized and so has a little bit better setup for music than Jellyfin, in my opinion. And it has far more front-ends on various platforms.
