This is why Boxset needs something new. Often a boxset can be literally that. A simple box. And inside the box is just six standard jewel cases. Six Releases that can be found elsewhere in the MB database with their individual Fronts, Backs, Mediums and Booklets. And here we have a new cardboard wrapper around them to make then a new set.
Puzzling.
Here is a simple example I added myself. This is a simple box, with six CD jewel cases inside, and the CDs are also available separately.
Here is a much more complex example. Only 230 images attached by another editor…
That one is a box set of boxed releases also listed as separate boxes! I think the labelling makes sense of the chaos!
