A number of users have asked for an option to prefer own metadata by default so I’ve opened a feature request thread to discuss it.
This thread can continue general discussion about other issues raised in Dan’s post.
The metadata providers are listed in Settings/About/Copyright Information and don’t include community based metadata so far as I am aware. Roon certainly pays Rovi (All Music Guide) for metadata, that’s one factor in the annual/lifetime costs.
@mike also recently referred to the need for improved metadata error reporting. What would you guys like to be able to do in that regard ? I think a template report that built up a database that remembered prior reports for an album would be good.
