First of all, congratulations for this great program.
My problem is that I use mp3tag for years perfectly but since yesterday I'm not able to tag files using MusicBrainz. Titles have dissapeared when I try to connect with it. Is it a problem of mine or MusicBrainz has restricted information to Mp3tag?
With the latest script, the classic mode of MusicBrainz works perfectly now. I was used to work with a template of MusicBrainz that searched album + artist and it doesn´t work yet but I hope that a new release of it is uploaded soon.
