You mean all of the six settings where “merge” is an option, don’t you?
Yes
And what option did you choose for “Production”? Roon or File?
Roon
I myself would never fill my own file tags with information about which three writers wrote the booklet essays in the various languages. I would never search for “all albums where the German booklet text is writen by so-and-so”. It suffices to read that sort of information in the booklet.
Another interesting, though slightly puzzling remark of yours. Do you imply that “Words by”, “Written by”, “Text” and others contain information supplied by TiVo or by the user’s file tags? I for one have never used such file tags. Mostly because of the fact that MediaMonkey does not provide those tags.
Others do. I am mother tongue English so “Lyricist” for a sacred text or a Shakespeare sonnet or a Goethe or Moliere poem just looks comical. It would seem that at least one of the metadata sources roon is using is commonly using “Text” instead of “Lyricist” for Classical vocal music and when roon aggregates data sources this will result in duplicates. If you follow this link you will see all the “roles” that roon considers to be a composer
Roon Knowledge Base - Roon Credit Roles
There are hundreds of them including “Vacuum Cleaner Arrangement” . But also dozens similar to a Lyricist, like Text, Words by etc. etc. that roon will also categorise as a Composer.
By the way, I thought that “Text” was meant for the text in the booklet, but apparently I was wrong.
Roon categorises “Text” as a Production role in the list above, presumably as the author of the booklet. So I am also puzzled to see “Text” credits treated as Composers.
Could you give an example of such a case?
