How can I delete some metadata for an entire library

[guardian1691]

I added the lyrics plugin and scanned my entire library before realizing I didn't have my metadata set to go in the same directory as the media files. I fixed it but now all of the songs technically have lyrics downloaded, so the nightly task doesn't make any changes. Is there a way to mass delete all of the downloaded files?

If it makes a difference, my server is on a Windows machine, and I know some metadata is in the ProgramData directory, I just don't want to blow away my entire server's metadata.

Stop Jellyfin, make a backup of the Jellyfin ProgramData folder. Then you can try finding and deleting all of the .lrc files in subfolders in C:\ProgramData\Jellyfin\Server\metadata\library\*.

Your other option is to "replace all metadata" for the music library. But that could affect any manual identification you had to do. If that isn't a concern, replace all metadata would be the simplest route.

That worked, thanks! Out of curiosity, why stop Jellyfin first? I didn't do that and didn't notice any negative side effects.

So you ensure that your database isn't being written to when you make your backup. Making a copy while a database operation is in progress is great way to have a corrupt backup.
