I'd have to disagree there on that one,they are not identical,one thing i have learnt whilst adding CD's,is that very often,each different country writes the Cat.No. differently.i.e
123456789 is not the same as
123 456 789,or 123-456-789,or 1234 567 8 9 (similar is not identical)
these are not just typo's,this has been done purposely,they have been deliberately written that way to differentiate each countries release,...
