Add MBID tag to downloaded musics

It would be really great if it was possible to add [MBID](https://musicbrainz.org/doc/MusicBrainz_Identifier) tags as some self host music servers (for example [LMS](https://github.com/epoupon/lms)) can use it for Scrobbling to services like [Listenbrainz](https://listenbrainz.org/)
