I have two versions of Stabat Mater Dolorosa by two different composers. I have tagged each work 'Stabat Mater' in the album field, but obviously composer, hence artist tags are different. Many of the other fields are the same because they both appear on the same release. If I leave it like this and scan the folder into my library neither of them display. When I change the album tag of one of them to Stabat Mater A, they both display properly. Any idea what is really happening here and whether is it possible to have files with different artist tags but identical album tags display properly?

Thanks
