Moving to a different country can be a real mess.
Many web-services doesn’t offers the same rules on different countries, Spotify is one of these.
Spotify free accounts can reproduce music on different country for at most 15 days.
After this time, Spotify FAQ suggest you to change your country in the profile page but you don’t exactly have all the countries available..
I don’t know if it’s a simple bug or a wanted behaviour, but I’m not going to the UK and I want my account to be transferred in another country RIGHT NOW! (without having to register a Premium account and change my payment method)
