“beets is a cross-platform command line music tagger and
organizer which you can use to ‘get your music collection right
once and for all’.“It can improve your music collection metadata by using
MusicBrainz, download cover art for all your albums, reorganize
your music files, fix filenames and more.“Further more, beets is extensible through plugins which add
extra functionality like embedding or extracting album art from
files, fetch lyrics for all your songs, clean up tags and and
there’s even a HTML5 web player (though it’s very basic and can’t
do too much for now).”
