It takes time to make all these updates
Note that I can easily do the update on IDs or title, but I don't filter on movie type. You include that in your search, but it would be safer to check for all kinds of entries, not just music videos.
Also when you give a list and "except nr x and y", that's complicated for batch-update too: in cases like that it is better to give me first the country of these, and then I update the others (in batch-update I only set the country for those which have none yet).
