recently I have been having problems with my walkman app. All the songs are shown multiple times i.e. I have around 450 songs, but the track list shows more than 5000 songs with each song having a minimum of 10 copies. I had to download another app to play the songs.. being a music freak its a sadness that I can't use the Walkman app which was one of the main reasons behind buying this phone.
Try settings-apps-all-walkman,force stop,clear data and restart the phone.
