Music deletion

[Sp12er]

How's the way to really delete music? After I delete a music(using File Explorer by PC), the metadata still there, still detected by the phones, but can't be played: "Can't play this file in your phone" error 80070003 displayed... Is there any way to refresh the music&videos directories?
