I bought an Xperia Z in Thailand 2 months ago. When I first unpacked it and switched it on I was wondering why I didn't have music unlimited app on my Xperia Z. Now I have moved back to Indonesia and try to download the app from the web and or from Google play store but I got notification that my device is incompatible with the app. And also I have updated my walkman app with the latest update but still my trackID history does not appear as a playlist on my walkman. Please, anyone can help?
