I just did a batch rename in Finder (using AppleScript), however the filenames in iTunes remain unchanged.
I tried restarting iTunes and that did not help.
I also tried iTunes >>> File >>> Library >>> Organize Library, but it happens to be grayed out, as I had already recently done this (prior to renaming the said files).
Any clue how to get these files renamed in Finder to show up in iTunes without manually doing so? It's too large a number to do manually.
