Handling of box sets

I apologize if this is already discussed in an existing issue.

I would like to discuss the way beets handles large collector boxes like [this one](https://musicbrainz.org/release/004f10a5-e20d-43af-af85-4a5df9669312).

At the moment, beets imports this as one album titled "Suivre l'étoile", composed of 300+ songs, which is very hard to navigate. This is a pithy in the case of a box set because unlike a compilation, the songs are grouped by existing release, so the CDs actually make sense*.

I'm aware that it is possible to number tracks per CD, and that it is possible to make separate directories for separate CDs. However this doesn't really fix the underlying problem that for a box set, it would be intuitive to be able to easily access the individual albums by querying their release name.

Having read previous issue, I'm aware that the crux of this problem is to be able to reliably identify when this is the case from the metadata provided by musicbrainz/discogs. So this might not be feasible, I don't know.

Any input is appreciated. Do you have (many) such box sets, how do you currently access them, and how would you ideally like to access them?

*What I mean is:
if it is a "real" (small) _n_ CDs compilation of tracks sampled from various releases, which were arbitrarily grouped by the editor and only numbered or maybe titled with equally arbitrarily titles like "The blue period", "1960-70: Artist in Paris", you (I) wouldn't really expect people to try to access to their songs based on those separations.
However, if it is a (large) _n_ CDs box set which only regroups pre-existing releases, maybe with slight modifications, then maybe you would expect people to try and access songs by their original album. Here the box set stands between the user and what he probably really has in mind, which are _n_ albums that he bought/got together because it is easier, or for price/availability reasons or because he was attracted in some extra features.
[I'm sorry this last part might be a bit confusing/too subjective, I'll try to edit this later.]
