It's not been working since 8.0 :p as the app itself is a joke. I put a handful of songs on to my phone for the gym, cycled through fine. I get there and they are no longer there despite the files are still on my phone lol. Same issue I had when I first got my phone (back in 2012), since I have Nokia music as a back up it doesn't bother me that much.
I get this error "error code 80070003" when trying to play my music.. and after MS has taken over Mixradio (after the unbranding update).. my music no longer plays... hardly surprising
