However, I understand the editors' frustration on this matter, there is a great feeling of... injustice.
If you want we can more formally identify works that have been claimed by people who didn't write them: musicologists like Carter, studio and label owners, etc...
It could be done with a work tag... does anybody have any proposal? "Misappropriated" perhaps?
This work tag could in turn trigger the display of a text string like:
The legal composers/authors of this work likely don't correspond with the actual composers/authors.
Working with a tag would even allow for new queries like "Most misappropriating artists"
