I was looking at this release:
https://musicbrainz.org/release/8f77fbb9-e959-4075-8c23-264243c154c1
and am pretty sure it is the same as this on Discogs, when reading the Amazon description:
https://www.discogs.com/release/3396131-Skraeckoedlan-Äppelträdet
The MB entry only has a link to an Amazon item. To me it seems the release date there was the date the item was entered into that Amazon shop. But is is a release date when a shop decides to sell an already released item? My idea is to add that Discog link to the MB entry and update the release date. But is that how the MB world wants it?
Thanks,
Jerry
