Feature description

A one-to-many correspondence, possible to combine and exclude when filtering.

Why do you want this feature?

To organize them in a manner which embeds into the audio file, or via the file system as FossifyOrg/File-Manager#60 (comment) requests, but via the Notes GUI for the sake of accessibility to the technically less competent, and convenience for all, regardless of competence.

Additional information

I'd go with ID3 tags since they are more common between various systems and apps.

Fossify File Manager can already display ID3 tags, so it won't cause any disparity for people using Fossify apps. Also, it would be confusing for less technical people, since extended user attributes are far less popular and many people may not even know these exist.
