Ignore metadata

[TheDreadPirate]

The movies, shows, and music library types are pretty rigid in requiring metadata and folder structures to conform to a standard. AFAIK, there is no way to just show folders in the music library type. I've never tried the music VIDEO library for for audio files, only actual music videos, but that library type does NOT read in any metadata and just shows files and folders. But then you may lose a lot of the music centric behaviors for playback.

The folder structure you describe IS supported, but Jellyfin is very dependent on tags. Musicbrainz makes an app called "Picard" that will auto-magically tag your music and even embed album covers.

I'm not sure how much extra storage you have, but I made a backup of my music just in case Picard screwed things up. But, so far, I haven't found an instance where it completely got it wrong. If Picard isn't sure it will tell you and it will preview the original vs new data before it commits the changes.
