I am a lifetime subscriber to Roon and have enjoyed it from day one, I would buy it again in a moment. With that context, I have some thoughts on the recurring questions related to quality of metadata, handling of boxed sets, reviews, etc.
It seems to me that the ultimate issue is not simply how Roon chooses to source and present meta-data, but also the quality and completeness of that data in the first place. Obviously, Roon’s supplemental information will be only as good as the data source. I believe that even were Roon to present metadata perfectly and in a manner to everyone’s liking, many of the issues cited by members of the forum would remain as the metadata source is incomplete & imperfect.
If there is not a 100% reliable and complete metadata source, perhaps the solution is to create an added and integrated layer of crowd-sourced metadata accessible across Roon subscribers. For example, I may take time to do my own grooming of a boxed set in such a manner that Roon can better present the set to me. I would be perfectly happy to share that revised metadata with any other Roon customer. Similar perhaps for reviews etc. Think of it as a Wiki for Roon customers.
One could see interesting uses of the data on the back-end. Perhaps Roon could sell a subscription to this data back to its existing metadata provider? Going further with the notion of shared data, it would sure be cool to see real-time aggregated data from Roon users: most owned album, playing now, total albums owned, genre distributions, etc.
Speaking for myself, while I am very sensitive to privacy concerns, I am a real fan of music (and Roon) and would be more than willing to contribute my metadata and library stats to make for a better music-listening community.
