The author of BubbleUPnP has informed me that a container is displayed with a Play button if its UPnP container type is musicAlbum and not if its UPnP container type is a generic container, with one exception. If the container is a generic container and its metadata includes an albumArtist value, it is displayed with a Play button. The containers for the Schubert works are generic containers with an albumArtist value and the container for the Britten work is a generic container without an albumArtist value. This is why BubbleUPnP displays the containers for the Schubert works in a different format than the container for the Britten work.
