It may not seem like there is a big impact with editing especially as it seems like very few sites/programs that use MusicBrainz data mention it. But I think it helps a lot.
And for what it’s worth, as a KPop nerd, I personally appreciate your contributions and the work you have done. As silly as it sounds I always look forward to seeing you working on a new artist as you do such a thorough job on the releases you add.
What do you use MusicBrainz for? related topic that might be worth a read for why others do the work on here they do. (In fact I will go update my post)
But as aerozol said, best to take care of yourself first. It’s your time to decide what is the best use of it. And also +1 for joining the discord. Several other KPop editors in there already.
