Why am i forced to buy in a certain Itunes store?

Question

Currently i am linked with the german itunes store which unfortunately doesn't feature a certain album song. The UK store offers this album/song though.
Trying to buy it i am being rejected telling me that my ID is not authorized for the UK store. Why can't i buy what ever music i want? It is digital and will pay for the song anyway.
So why do i need to wait until a local store manager sees my country fit for a certain release?

Unless you can show some form of residency you cannot buy from another country's store. The question on cross store purchasing is asked frequently so I'll just quote the most complete answer (courtesy of Dave Sawyer) from the many given:
In order to buy from any given country's iTunes Music Store, you must have either:
a) a credit card with a billing address in that country, or
b) a mailing address in that country and a gift certificate or a prepaid card that was bought in that country.
If you cannot fulfill one of these two sets of conditions, you will not be able to purchase from any given country's iTMS.
.......this is due to restrictions placed on Apple by the record companies and other rights holders (who are often completely different from country to country and so all require their own individual negotiations and contracts), not by Apple's choice. And this also applies to all the legal download stores that carry major-label content, not just the iTMS.
