Artist names in Japanese usually include a separator (a middle dot “・”) between the first and last names (e.g., Dvořák), but in rare cases, it is missing (e.g., Vivaldi). Since AllMusic does not provide Japanese names, I assume Roon configures them independently? Who should I contact to request a correction for this?
Roon uses some third-party translation service for artist, credit, and genre names.
I’d suggest you post these various issues in Support just like you have for one of them. Or perhaps keep them together in your support topic. Roon Labs doesn’t normally monitor Roon Software Discussion as it’s the user discussion area.
@Suedkiez Thank you for the additional advice. I’ll contact support right away. I had wondered if there might be an expert here who knew something about it, but contacting support is likely the quicker option.
