my changes (tested only by me):

Spoiler:

    def _remove_itunes_plist(self, container):
        self.log('\tLooking for iTunes files')
        removed_itunes_total = 0
        for name in list(container.name_map.keys()):
            if name == 'iTunesMetadata.plist':
                self.log('\tFound iTunes plist file to remove')
                container.delete_name(name)
                removed_itunes_total += 1
            if name == 'iTunesArtwork':
                self.log('\tFound iTunesArtwork file to remove')
                container.delete_name(name)
                removed_itunes_total += 1
            if removed_itunes_total == 2:
                return True
        if removed_itunes_total == 1:
            return True
        return False
