Is there a simple way to propagate all the recording data back into the release, merging artists or overwriting track names as needed?
The existing boxes in the edit dialog, I understand, all work in the Track->Recording direction:
"Update the recording artist credit to match the track artist credit. "
"Copy all track titles to associated recordings. "
So, how to go the other way, propagate Recording->Track (with a few clicks)?
Before getting too carried away with changes, please have a look at the Classical Style Guide which explains the differences in the way that classical music is entered as opposed to non-classical. Of particular interest might be the sections on Track Artist versus Recording Artist. I’d hate to see you put in a lot of effort only to find that it was contrary to the official style guide.
