missing music files

[Stainless 313615]

My music files have gone missing since my samsung upgrade. I went into my files and found it listed under albums but when I tap. It says no app to open. And 0kb for that file. How do I retrieve these lost files?

Welcome to Android Central! Where were the music files stored, in Internal Storage or the external SD card? I have heard of issues where the external SD card got messed up during a system update.
