all music gone nothing works to reload
I have a Itouch 4 and lost all the music on it when trying to switch some music out. Since then, I have tried just about everything and can not get any music reloaded. Can anyone help? I've tried syncing, rebooting, leaving it overnight to have time to move music over - nothing seems to work. I'm at the point of restoring it to factory settings and just starting over. If there is a fix out there - please let me know!
iPod touch, iOS 6.1.6
