They are wav- files and seems that part of them are corrupted so that information is wrong. You can´t copy them and when you play them with player it stops when song reaches corrupted place. When opening them with wav- editor the curve is just on the top in corrupted place.

I defraggled my 2TB hard disk when it was over 90% full (100MB free). After very looong period and couple times stopped and started again, because power save was on and stopped hard disks and I turned computer off, but only by using "stop defraggling" I noticed that many of files are corrupted and cannot be copied to another HD. Why?
