No need to worry buddy. Some update changes your sence me and walkman app.
if you badly need that,then you need to install a new walkman app.
google out if thre is any new walkman app or try the hard way(only if u r desperate )
->root ur device
->install root browser
->delete the old walkman app from /system/app/walkman.apk
->copy paste another walkman.apk to the above directory
->change permission to rw -r -r
->restart phone
and the most important step
dont forget to give kudos :smileysmileywink:
