keerthi, I'm not too tech savvy with the phone. Basically a while back I updated to the developer preview and I'm not sure I ever actually updated the XBox music app, or any app if it didn't do it by itself, or when visiting the Store. The music player looked different than the 8.0 when opening so I just figured it was updated. It opened and worked for a while, even though it had the "loading..." for a long time. But like I said, XBox Music (the native player) won't open at all now. I've kinda given up because I do use a different phone for everyday use now anyway. My Lumia 521 is just in a drawer, but I turn it back on every once in a while, and turn on the wifi, just to see if it fixes itself. It hasn't . Sorry I'm no help. I'm kidding about the "fixes itself" part.
