Thanks go to everyone who participated in the development, most notably Lukáš Lalinský who ported picard-0.7 to python-musicbrainz2, created binary packages and has contributed bug reports and patches.

Not sure if you guys have already implemented this feature or not, but I’m currently using MusicBrainz Picard and I would definitely like to see a new feature added. Is there any way to use the tagger to change the comment on tagged files? If you could set a blank comment or your own personal comment in the preferences to be written to every tagged track, that would be amazing. I’m loving the program though, keep up the good work.
