I am observing a couple of odd misidentification of Bach works that seem to be based on some Roon magic ;-).
Cantata BWV 198 (Lass Fürstin, lass noch einen Strahl)
Cantata BWV 199 (Mein Herze schwimmt im Blut)
For some recordings, like the Bach 2000 box set, the cantata BWV 198 is attributed to recordings of both BWV 198 and BWV 199.
What I find interesting, is that both works are attributed to BC A120. I have no access to a proper list for the Bach Compendium Catalogue, but it looks to me as if there might be some issues due to the same BC key used by two different works.
For the Harnoncourt/Leonhardt and Rilling recordings, both works are attributed to BWV 198
BWV 542 vs. BWV 543, both having BC J42 as a shared key
Of course that’s only an outside observation without any claim to be the root cause for this, but maybe @support could look into this?
