z1 music issue
i have been transfaring music from my PC to my Xperia Z1 and iam having an issue with some music on the walkman app displaying "cannot play track" ...
all my music (MP3 files) have all came from the same source and as far as i can tell they are all MP3s
i have tried using another music app (rocket player i think) and it doesnt even pickup that the "cannot play track" files are there...
can anyone help me with this one please
