I used to use the WORK & PART tags in Amvidia's "Tag Editor" to separate things in Roon. It was usually classical music but it is also a useful feature for albums that contain multiple things that can be collected under different headings, as seen in the screen shots.

So, I had a go in Yate & I think I can see what I need to do (having done it in Tag Editor & seen how & where it subsequently shows up in Yate). [That is to say, create a user defined text item called either WORK or PART & enter the text.

That's fine for the part that will be the "work" as it will apply to all the selected tracks. What I can't figure out is how to apply the PART tag to a selection of tracks in one hit, as they each seem to be in their own "user defined text" entry.

I'm sure it's very simple, as always. 😀

Thanks!
