Disc subtitles of incomplete albums

[simoncn]

Changing this would not be easy. Although it looks like the only difference between the incomplete album view and the complete album view is the presence of disc dividers, the underlying data structures (object models) are very different.

An incomplete album just contains items (tracks and/or groups). A complete album can contain items or it can contain discs and these discs can contain items. The disc divider is produced by the disc object and can be selected to show and/or play the disc contents. This cannot be done for an incomplete album because there are no disc objects.
