I think the full error as reported would probably be helpful. Steven knows what all the doodads and wxyslwidhgovlcie13le type codes mean.
More information about what format music files these are, where they are on your system (a NAS, internal drive, thumb drive, etc), what kind of tagging they carry, and whether you've checked their integrity with file verification tools would also be helpful.
Not a lot of information to go on here besides "nothing works and nothing fixes it."
