Undoing iTunes folder organization

You can't undo it in iTunes, however there are music organizer programs. Google - organize music folders.
I came across this link:

I have no idea if any of them are any good, you would need to research them thoroughly before chosing one.

Perhaps someone else has a recommendation.

* BUT the trouble is that iTunes will get confused if you change anything and you would have to recreate you iTunes library from scratch if you do this, is it worth it? *

Though you can't undo iTunes's folder organization, I believe I've found a way to defeat iTunes.

I used Automator to (a) find all files in the iTunes Music folder which had an extension of m4a (don't use a period before the "m"); and (b) copy all found files into a different directory (if you're feeling confident you can have Automator move the found files rather than copy them).

I have 45,000 tracks so I set it up last night and when I got up this morning, all the tracks were moved over.

The next step is to highlight all songs in the iTunes application and delete the songs (but NOT the files).

Next, you go into iTunes preferences and uncheck the "Let iTunes organize your collection" choice.

The final step is to add the songs in the new folder into iTunes. My report from home is that all the songs came back in, with full metadata, sortable by any field for which there's metadata.

This was relatively easy, and let me, if not undo iTunes organization, at least explode the entire structure and start again.
