Query metatags, no extenal DLL's, or exe's needed.

This is my most recent discovery for auditing multiple audio file metatags...
These files are the back-up of my iPod

There's a lot more here than is needed - But I wanted it to look nice.

There is also plenty of comments and methods in it, to give you an idea on what kind of audits are possible.

Previously, I used ffprobe (part of ffmpeg) to read these tags... But it was kinds of slow...
What I used here, took less than half the time.

To see what I did with that "$NullQuery" from this script, see this post:
