I want to stress that this is about TRACK level editing, not album level editing, which can easily be done on multiple albums at once.
The problem arises from my file and metadata structure, which is not wholly compatible with Roon for Classical albums.
With my setup, Roon will always derive a Primary Artist from the Composer, leading to absurd track information that say, Beethoven, performs on all the tracks.
This cannot be edited out at album level, and requires editing of the credits at track level. It is a very very tedious task doing each album individually, as there are several thousand of them.
What I want to know is, can I edit the credits on multiple albums simultaneously at TRACK level, to delete the spurious Primary Artist entries?
It appears that I cannot but I am hoping that somebody can show me that I am wrong!
