http://reports.albunack.net/mbartist_discogsartist_report2.html is very interesting, we could start a community effort to create missing links.
Those 60k artists aren’t counted in http://reports.albunack.net/discogsartistnotin_report.html (“These are Discogs artists not currently linked to a MusicBrainz artist, and we have been unable to find a potential link for either.”), right ?
