Hi.
I wanted to make this post because i searched the net and i did not found any results on the xperia P walkman bug, and that bug behaves so: i play the song i want, and after a couple of seconds it gives me "cannot play song" the problem persists at certain songs in my library and this started to happen after the 4.1.2 JB update.
I searched in here but found nothing for my problem, if anyone had this little bug and got it fixed please post.
Thanks for your time and have a nice day. 
i used the update service, and then did a factory reset with SD card format, and the problem persists....meaning that the problem it's not on the phone, it's on the song.... 😐 but i don't understand how this can happen when on the previous update thoes specific songs were playing with no problems....
You mean the songs are the ones with problems?Try to delete LOST.DIR folder in sdcard.
done that, did nothing....problem still there... *sigh* and idk were the problem is because as i said above, the exactly same song worked on the previous update....so yeah....
It is only one song that makes you trouble?
nope, there are more idk how many but i estimate around 10..less or more...need to identify how many.
