My biggest issue with Xbox Music is Duplicates. I got rid of my Zune HD expecting to have a seamless experience across all my Microsoft devices. But now, I don't know after how many updates later I still can't sync my music without having the same songs repeated on my phone. Since they're dedicating their resources to Windows 10, I doubt they'll ever fix it. I mean, how hard could it possibly be to integrate syncing into Xbox Music when Zune and iTunes does it so well? I bought an iPod Touch because of this. But I'm tired of using 3 programs(Xbox Music(cloud matching), Zune(song credits), iTunes(obvious)) and 2 devices to manage my music.
Anyways, I haven't given up waiting... but I'm gonna wait til they get my issues with their app fixed before buying another Windows Phone. Who knows, maybe they'll fix it with that OneDrive locker. For now, I'll try another platform. Microsoft doesn't care enough for WP anyways as even their own apps are released first on other platforms, though I could care less if they fixed my music experience at WP.
