Thanks for those links, @Suedkiez.
I’m going to look at them much more closely later…
Is there any way for us users to edit (= correct 
) such metadata issues?
My first impression - perhaps re-inforced by what you say here, @Traian_Boldea - is that I am coming up against a limitation of Roon itself. Possible?
If so, that prompts me to:
- say that - as a lifetime owner - this is a small issue and one which I can ignore, so outstanding is virtually everything else in the wonderful world or Roon
- remind myself that when I first started using Roon (three years ago) I was strenuously advised by many good people, who obviously know this system ten times better than I do, to let Roon and its AllMusic lookup do the work; and not to spend too much time (in my case meticulously editing files in Yate)
- ask for your opinions and guidance on whether it’s worth opening a support ticket to have Roonlabs weigh in: I’d have said the fact that - for the disk icon - sometimes I do indeed get alternative versions available elsewhere outside Roon and sometimes just a list of what I’ve already got, and sometimes nothing at all is not right (a bug).
- wonder whether it’s still not me who’s missing a setting somewhere …
Again, your input very much appreciated.
