I move my mp3 files to a flash drive to make room for my pc. I reinstall them back but some of the files don't play. It has the name of the song but the info that useto show artist, album, genre, length, doesn't show. I sheck the size of the film to make sure it was the same size that transfor over. Can someone help me restore my my music.
