I started by relating the vocalists of the opera Akhnaten to the respective recordings. I thought it would be a good idea to add their roles to the vocal credits as well. For example:
But it somehow seems wrong. On releases soprano vocals are credited as “soprano” and not “Queen Tye”…
On the other hand, there are other releases where exactly that has been done (e.g. back image of Koyaanisqatsi → “Voice of Koyaanisqatsi” - not “bass vocals”)
And a recording should be independent of the specific release…
Should I continue with that? Or should I remove these “credited as” entries and put the roles in an annotation? …or leave it altogether, because there’s a list of roles and performers on Wikipedia, including this performance (“CBS recording, 1987”)?
This breaks user expectations of how the %performer% and %instruments% metadata values should work in Picard (and also all webservice consumers as a whole). e.g., “Moralès” isn’t equivalent to “baritone vocals” and can’t be consumed correctly by users of the MusicBrainz webservice. I’d expect “Moralès” to end up in the artist credit if at all, rather than in the name of the vocals.
I feel like this is solved by the fact that it is linked to the vocal part (i.e. baritone vocals), is it not? for example, Picard can easily standardize this performer credit with a checkbox in the settings
