I just got a late Tango update for my phone. When it was installed, I went wandering around in the settings.

When I got to music+video settings I clicked the Zune account link, and first got an English Xbox page with music added, including a link to the pass. I clicked that to see where it would take me, and got a Swedish Xbox themed page telling me how the pass would allow me to access music for a fixed monthly fee.

Then I clicked something else, and now I seem unable to get back to that page again. But the existence of a Swedish translation seems to suggest that something is planned.
