When to merge RGs - Soundtracks/scores of different nature for the same film/game

[jesus2099]

I think it would help to have something like franchise (ugly word), then game/film, then release groups (not merged):

Is there a standard way to group film scores by franchise?

I’d like to tag my Empire Strikes Back, Return of the Jedi (etc.) soundtracks so I can create a “Star Wars” smart playlist. My first thought is to just do something that “works for me” like Franchise=“Star Wars” and Episode=4… but is there a “proper” set of tags to use for such things?

With this, I feel that it would be more accepted to keep OST versions (release groups) separated.
