I know this has come up before, but my frustration level continues to increase. Roon has improved its grouping of movements within a composition for unidentified albums. It now seems possible to control that process.
But for identified albums, the data is wrong some of the time. The movements don’t always form a group under the composition. It seems this is more likely for rarely recorded works. The user has to be able to group movements while retaining the other internal metadata.
