All music files were labeled by "a" through "z" generally going to 100. But this was not done systematically. So a lot of work would be needed to go through old files to see what is worth while to save, or what is worthwhile to edit.
For example: this file. It was finished some months ago, but I thought to go back and take a look at it to see if it was worthwhile to do a bit of editing, and then present it. So here I am presenting it for the first time though it was finished some time ago.
