I can’t get the track titles to show up on this release. I’ve tried many variants editing the FLAC Tags but the titles always show as Part I, Part I, Part II, etc.
When this happens, to get the correct composition hierarchy with local content you need to set the WORK and PART tags to match the canonical form you can find on allmusic.org:
Both roon and allmusic are using the same Tivo metadata sources and this is why this works. I use mp3tag, a windows editor but I understand that Yate for IOS has roon tags like WORK and PART preconfigured. This is an extremely common editing task with roon classical libraries I am afraid
You can also set the “Part” SECTION tags if you want. I tend not to bother with a composition like this with only a few movements as I don’t like the clutter.
If it is a streamed source then your options are limited. Sometimes you can fix the hierarchy with roon’s limited editing tools but it is much more hit and miss.
PS: I have just realised that roon will set the section “Part” formatting whether you like it or not if the composition has been identified.
