How stable are the changes supposed to be in SongKong? I am using 6.2 Pro, no iTunes link. Unleashed it on my whole library (about 30K files) and after it finished, I ran it again. And again. I think 8 times so far. It never comes back “clean”, it’s always “fixing” something. Sometimes it moves a file from AlbumName to AlbumName (1) or some such, and sometimes moves it back on subsequent runs. One time it said it scanned 80K files.
I’d love to feel like SongKong has done all it can, but I’m not sure how I’d ever know that.
