My computers do not end up with the same music collection after iTunes match is selected.
I have 3 Mac computers using the same iTunes ID under Mountain Lion, with iTunes match enabled. After a few days of syncing, I would expect all 3 music libraries to look exactly the same. But they don't. Some artwork is missing. Some albums are missing. How can I end up with a perfect match with no loss?
