I have noticed that two of the movements in the Faure Reqquiem (1890 version)
namely “Pie Jesu” and ”In Paradisum” have additional “part of” relationships with other works
Soundtrack “CHAPTER IV PIE JESU (REST)” - MusicBrainz
and
I don’t understand what what first one is; the second is a soundtrack. It seems to me that the logical relational aspect of the MB “part of” relationship fails to capture some information - namely is there a true “parent” of the work. Clearly this would be a difficult question to resolve as a movement could be “part of” a major work and also of a revised version (although the Faure Requiem has not been entered so). While that would be legitimate, the others seem less so.
I found an older thread
which discusses this and the concensus seems to be that such links are not legitimate and should be removed. Is this still the current concensus? Or is there any actual policy? What, if anything, should be done in this case?
