I preface this with yes, I understand that it would not be easy given there is in all likelihood, no online database with this information from which Roon could source it, but…
I would love to see information on where and how the recording was made, ie: Which Studio(s), which recording method, be it Analogue Tape (Studer, Ampex etc) or digital (Sony DASH, Mitsubishi, Alesis ADAT etc), Mixing console (Neve, SSL etc) and even down to the outboard gear used etc.
Difficult, but as a collective we could surely build on the database if Roon enabled such a feature, ie, not relying on external database but rather created their own?
I dont think that you and me as a user should or need to have solution to a problem .
Or tell Roonlwbs What kind services they should priovide.
I think it us much better If we/you focus on What would be good for you/us and What does have valure for you/us as a user, customer and consumer of content.
