Yeah, it would be a good solution too. If Picard could use MB linking to virtually “merge” different artist alias in one entity (basically the “root” one) for the music player - it would be good. In that case i suppose it would be ok to link IPIs with separate artist entities and then link it to the “root” artist.
It’s very hard to talk about “projects” at all when you work only with PRO data and when production music composers dont have any official sites, social nets, wiki pages and etc, so basically you only know them by legal name/aliases + IPI number in databases.
