for 4 of my albums all the songs and the albums names come up as random amounts of ?s. i dont know how to fix it, i tried re-downloading them, and taking out some characters from the names but nothing will fix it. so is there any way to fix this or what is the cause. and is there any way to change name of songs and albums on the phone by just using the phone. thanks and i know my grammar is not good but thanks for tolerating it.
