If you have musicbrainz identifiers in your file, it is assumed the other tags (artist, album, etc.) are correct and are directly used.
This is the first time I heard of AcousticBrainz and its sig (https://acousticbrainz.org/e73f3d92-4e9f-4db4-943a-41978d9db...). Nice! From the ones that brought us MusicBrainz right?
> what do you have in mind actually? I am not sure since the goal here is to play the music on the device from which you access to the server.
ncmpcpp is a music client, but for the mpd music server. Not sure if LMS <-> MPD do the same things. compare ncmpcpp to mpc, but w/ ncurses + c++. It has directory-based navigation which makes it easy to move through music.
Look forward to watching this project grow!
