Hi.
From time to time, I need to update meta data of MP3 files which were already previously imported into iTunes. I use Mp3tag for this.
iTunes doesn't reread a file, except (1.) when playing an MP3, when (2.) "Get Info" is selected from the context menu or when a rating is chosen for that MP3. There might be other features which also touch the MP3s, but none (I found) is considering more than one single MP3.
When many MP3 files need to be updates inside iTunes's database, this method isn't suitable.
This is a link to iTunes VBA scripts:

This the entire article:

Apparently, iTunes doesn't provide a feature to force multiple MP3s's update of its internal MP3 database.
