Xbox Music App Error

[aps_edu1]

Everytime I try to play a mp3 from Xbox Music App on my Lumia , It gives the error " Cant play.. Sorry ,we cant play the file right now. Try again Later" I.e without any error code.. This is happening with every song except 1-2 songs being exception..only god knows why only they are playing.

* soft reset not working
* File manager is playing all files.

Any Ideas folks
