Cannot Rename Certain files

I'm having trouble renaming certain files in a group.

I'm trying to add a random string of 4 letters to the beginning of a large group of music file names so that my fm transmitter will play them in a random order. But there are a handful of files that just refuse to be renamed.

I keep getting this error:

"101 Unknown Error: the process cannot access the file because it is being used by another process."

I don't know what other process(s) might be using those files. I've tried shutting every other program down except Advanced Renamer and File Explorer and even rebooting. But nothing seems to work. I can rename the files manually, but that involves several hundred files. Just not practical.

Any ideas why this might be happening?
