You may spend money purchasing some songs on your mobile phone and accidentally deleted or lost them. Then you can get them back from backup, but unfortunately some persons don't have such habit to do periodic backup in daily life. For those who have no backup for lost data like music, I would recommend them using 3rd party software to retrieve them. Gihosoft free Android data recovery is one of reliable tools to recover music from Android phone, the most important is that you recover music, audios and voice recordings via this software[b] for free[/b].

Hope the video tutorial helps:
