I really want ot upgrade to windows phone 8.1 but I am hearing a lot of bad press about the "Xbox Music" app. I hear that the "Xbox Music + Video" app was replaces with just the "Xbox Music" app and that it is slow moving, loads slow, the audio controls suck, etc. The music app is really what keeps me on a window's phone because I love it and I don't want to upgrade to 8.1 if the music app is as terrible as the articles suggest. Is the "Xbox Music + Video" app still implemented in the phone? By that I mean, can I still use the same old music player I had on 8.0 with the 8.1 update?
