looking for accessible music library app

[Linux for blind general discussion]

Of course we can run Musicbrainz and such. But the filesystem 
organization method will allow organizing files and directories in 
whatever way we want, even if it's based on information that is not 
available from Musicbrainz or a similar service, or even information 
that cannot be put into tags. Library databases are actually quite 
limited in what they can sort on and how they organize music. Best I've 
seen is genre, artist, album, title, maybe release year, and then 
there's "all songs" or similar. Nothing matches based on country or 
continent and other external information that is never put into tags.
