# When a Series has sub-series, should a Release Group be present in both series or only the most specific level?

I notice that [Do not cluster - MusicBrainz](https://musicbrainz.org/doc/Do_not_cluster) is “no longer” a guideline, but still something we’re supposed to keep in mind. Should we be applying this to Series and sub-Series?
For example, [Release group “Xenoblade Original Soundtrack” by 下村陽子、ACE+、清田愛未 & 光田康典 - MusicBrainz](https://musicbrainz.org/release-group/22d84e56-4266-4905-8abc-2db79c3a0a4d) is currently a part of the specific series [Xenoblade - MusicBrainz](https://musicbrainz.org/series/e2d9d3fe-ee73-4a85-900f-b727a19f4b04) but it used to be a part of the generic parent series [Xeno - MusicBrainz](https://musicbrainz.org/series/c604e5d3-2a72-432d-b401-d2aa4aa69fb0)
Is it ideal to link the Release Group only to the most specific Series? (The most specific Series is a subseries of a parent Series that does not get a direct link to the Release Group.)
For a larger example, consider [Dancemania - MusicBrainz](https://musicbrainz.org/series/d316d733-9d75-4eb3-aa41-f0fcf6f502bd) which has a dozen subseries - we don’t want to link hundreds of release groups to both the most specific Series as well as the parent Series, right?

I think we should only link the RG to the specific subseries and then let the hierarchy of series do the rest of the work.
If it is a part of a subseries, it is included in the bigger series so it’s redundant to add it twice IMO

Maybe a toggle or tab that shows all releases in sub series in a series window would be a good idea? Shall I open a ticket?
Because I have the opposite opinion to @Totosaurio3279, when there’s heaps of subseries you might still want a place where you can view all the related releases, without clicking through to each lower level and then keeping a bunch of tabs open.
e.g. If I want to see all Xeno releases in release order it’s not necessarily helpful to be pointed to a page with links to 10 sub franchises
This is case by case obv, sometimes not linking them might make sense. In the Humble Bundle series I ended up taking out audiobooks from the parent series because it was getting v. messy:

Well, that might be true, and I actually use a funcion like that a lot in VGMdb when I search for a franchise, but for longer ones it does get very extensive like [this example](https://vgmdb.net/product/3559).
I think a toggle could work really well, or… well, maybe moving the subseries to the top like in VGMdb? If it does get REALLY extensive I most certainly don’t want to scroll a whole lot to find such important data

I think so, yes.

This could be nice, indeed.
Note how for areas we display all sub area entities: [France - Artists - MusicBrainz](https://musicbrainz.org/area/08310658-51eb-3801-80de-5a0739207115/artists)
Here it could be better to display sub series entities only after some click, like for sub-works with @loujin userscript: [musicbrainz-scripts/mb-display\_split\_recordings.user.js at master · loujine/musicbrainz-scripts · GitHub](https://github.com/loujine/musicbrainz-scripts/blob/master/mb-display_split_recordings.user.js)
