I bought a new xperiaZ2,and I enjoy playing music with Walkman.Recently I put some songs via USB from my PC to it ,but Walkman can't find them.they couldn't be played until I open file commender,find the song ,then it can be played.but neither can i edit the information about the song opened in file commender in the Walkman ,nor can i put the song in the list .and it shows wrong album covers.(but i have deleted this cover's picture )
sensme just recognize inside songs,but doesn't recognize my own songs .
[P.S. I am a Chinese user and I uninstalled its insidemusic app: DUOMI music(DUOMI often can't work nicely ) .before uninstalling Walkman worked finely .Is Walkman's bad performance associated with my uninstalling ?if so ,could i reinstall it again?
