I recently switched to a Lumia 820 and was deeply disappointed to find out that my favourite app isn't available in the Store.
As a Premium user i consider canceling my account, since WP8 has been release on October 29, 2012.
Concidering the fact, that the release of this platform has been announced a long time before that, one can argue that enough time was given to Spotify to provide us with an app.
I know its release is planned for Q1 2013, but that information just isn't good enough for paying customers, since they can't use your service until then. Would you rather us cancel our subscribtions or would you grant us a refund until the release day?
