I’ve cleaned up Jazz part of my collection as it is easier than Classical. I’ve added missing releases and tagged it all. To my surprise, 110 albums out of 385 (about 30%), have zero performing artist credits, either at the recording or at release level. At the same time, some of the releases are very popular in the Jazz world, for example:
Discog links points to a release group where individual releases have detail artists credits per track.
Is there a user script which can populate recording artists credits from Discogs to an existing MBNZ release ? I looked, and besides Discogs release import, have not seen one.
