That is ridiculous, Hungary is absolutely in the EU - completely. Being a part of the Eurozone has nothing to do with being part of the EU - it does not endow the countries in the zone with any extra legal power - it is just an area with a single currency.

The UK is not in the Eurozone. It has an iTunes Store. The Eurozone does not have a single iTunes store.
