I’ll invite @Ludwig into the discussion - he is another user who has experience in wrestling with Roon’s way of dealing with classical metadata. But really we need to hear also from the Roonies themselves - they are the ones who develop the algorithms. Insights from them are sorely needed. I’ve already invited input from @joel and @vova earlier in the thread, but no response from them as yet. I suspect they are still dealing with the aftereffects of the 1.3 release.
I find it slightly ironic that @kevin invites submissions from us on the topic of “Best practices for organizing and navigating a classical music library”. At this point I haven’t got a clue where to start.
