First, can I say I love MP3Tag! An amazing piece of software!
I've recently been re tagging all of my music and now I've finished, I've just found out about the Music Brainz IDs!
All of my music now has a "Album Artist", but I've checked and not all my music has the field of "MUSICBRAINZ_ALBUMARTISTID" set.
Is there any way of finding the UUID from the "Album Artist" field, looking this up and putting the UUID into the MUSICBRAINZ_ALBUMARTISTID field automatically? Or any way of doing it better than manually going through my artists, looking them up on Music Brainz and copying the ID into the field?
