And quite often it's the bands - typically the bands manager will ensure the publishing and distribution contracts are limited to specific territories. One reason behind that is that when you start out as an unknown in your home territory, it's difficult to negotiate a great contract, but once you've got success, you can get better deals in a second territory. Of course, these days the nature of the business has changed dramatically - but I think it would be wrong for Apple to force publishing companies (and therefore musicians) into global contracts, much as it may benefit US consumers.
