If I have the USA copy of SingStar, I won`t be able to buy from UK Singstore and vice-versa, right?
You can buy from there if you have a UK PSN account and a way to get funds added to it.
So the music added via PSN are not bound by region? (just to get that clear)
Ah, and thank you for your help!
At least for SingStar that is the case. I have some songs I got from the UK store that play fine on my US version.
