Well, that’s fun and interesting. Several attempts at removing / reimporting later, I found that results would not change. But in between importing and quitting, if I used “Show in Finder”, it decided to open one of the missing tracks–right out of the trash. Emptying the trash, deleting the album, quitting the app, relaunching, and re-importing seems to have worked. Watching the activity window, it even worked its way through sound check information.
So, I guess it can be made to work–Apple Music just can’t be trusted unless you’re prepared to quit app and review that every import matches what it should. ‘Cuz that scales so well \o/.
Yeah, my urge to press my old ThinkPad or Latitude into song management duty is rising.
