I formated my sd card as internal storage and basically everything went fine and then i tried to copy some music through my P.C and when i was looking for my sd card in my P.C files i couldnt find that...but my phone's internal storage is can already see through my PC files....and then i copied some music to the internal storage and later i move them to the sd card through my phone, and then i looked for them in the google play music and i couldnt find any music which i previously moved....but after moving them to internal storage i can find them easily...please help me with this matter..thankyou.
