I'm a Belgian premium user of spotify since almost 4 years.
Always very happy about this solution that I recommend to everybody.
I live in Indonesia now for the last 2 years and continue to use my Belgian spotify account since that time without any problems.
What a great news today to read that Spotify is finally available in here ! So my first idea was to move my country but I'm not able to do it..
I followed the tutorial in the spotify FAQ to change the country and the method of payment, but I can only chose another credit card number. But I know that I can have many diffent payment options like bank transfer, payment in shops, etc.. in here. And I'd like to use one of them but Spotify doesn't allow me to change the payment type. from credit card to "cash" solution.
I kept my belgian credit card and bank account open, only for spotify and I'll be happy to cut it and pay my account in Indonesia as I'm a permanent resident.
