Hi,
I would strongly second the request. See also my post from two days ago:
How does the recognition of classical works work…?
As I have stated there, a fourth of my collection (around 1800 albums) is not recognized by Roon and I am certainly not going to match it album by album manually for several reasons:
- I already have tagged my collection consistently throughout and I don’t want external metadata - why should I spent time in matching metadata I already have…
- I want to have the work names as I like them and in my mother language
What I also would like to request is to globally prevent Roon from matching my albums (maybe that’s already possible and I missed it). Very often the matched master data is not recognizing the works correctly (often a work is split up in several groups), so after Roon did the matching, my metadata is worse than before. I could do that album by album manually, but that’s not an option for me. But again - I may have missed something.
Is the existing tag-mapping (Work, Composer, Soloist, etc.) documented somewhere? As I have written in my post, there seems to be more because it doesn’t work for me in the way you described in some cases.
Sorry for hijacking your thread…
