Thanks for clarifying it does indeed resave them all on the right. I was looking for some settings or right click option where it would only select the ones where the little CD icon has a star over it signifying an update, but couldn’t find that so posted here.
I did try the “Remove Perfect Albums” plugin @outsidecontext but that seemed to take an incredible amount of time too, maybe it’s because a lot of what I usually scan isn’t a full album, but maybe only a few songs from one, but totally guessing there.
So for now sounds like I’m kinda stuck letting it run for hours and resaving everything though, correct?
