What would you do if they’re all different?
The name of the first release doesn’t always seem to be best (see ‘soundtrack book’ example in op), it can just as easily be something wacky and unhelpful as later ones.
This is a massive can of worms that I don’t know if we will find ever consensus on. Interesting to talk about though…
A game does have audio in it. It is a release of music, with a date, art, publisher etc, that someone has written and someone has performed. It’s the same with a film release.
However I’m not necessarily saying everything should be added to the database. It would probably need a new type of release status/some UI updates to handle it smoothly. Maybe a new entity.
VGMDB (video game music database) recently-ish added the capability to add composers etc to ‘game’ entities that don’t have a soundtrack release. It’s a huge improvement to their dataset. If someone composed music for a game/film, why should they not get credit for it on their musicbrainz artist page just because the studio didn’t put out a soundtrack? And most people who are interested in game rips aren’t interested in the date of the rip, they want to tag with the game release date. I’m not saying that’s in line with MB policy, I just want to acknowledge that there is a group of people not being served by the current state of the data.
Again, not saying we should immediately add every game and movie, but it’s interesting to think about.
edit: wonder what @CyberSkull thinks
