So it looks like the Tchaikovsky first piano concerto has some funkiness on MB. The original version has basically only a tiny handful of recordings, and almost all of the recordings are of the 1888 version. Yet the 1888 version doesn’t have individual movements broken out as separate works, and almost every recording on the MB service was tagged with the original 1874/1875 version. My thought was to take the existing separate movement works and change them to be the 1888 version separate movement works instead of making new ones for 1888 and then changing almost every recording on the whole service. What does the community think?
That seems to be the easiest solution to fix it. After changes some other services (wikidata?) might have incorrect MBID for the version but I’m not sure how commonly these are used. I would still recommend making edits you proposed.
There’s discography provided by Tchaikovsky Research which can be used to identify the recordings of rarer versions.
