iTunes Music Store - Different countries

When I try to buy a song from iTunes from a country's store other than the US, it says I need to have an account registered for that country. I don't really want to make a whole other iTunes account, so does anyone know a workaround or anything for this? Thanks.

AFAIK, you can only have an iTunes Store account in the country you live in. Here in Aust the iTunes Store doesn't sell movies yet and I don't know when they will be available either.

I wonder what another countries iTunes Store has that the US Store doesn't?

It seems to me that other country's music stores have different songs than the US one - I mean not all totally different selection but there are a lot that I've tried to find in the US store and just can't, but are in another country's store.
