hey this is kuzya,
you are in the folder called source,
which contains the .json source files used to create the songs.
Unfortunately, some of the source files were lost to time, but the mp3s remained intact,
The only song that the source file of remained is Firefox.

If your curious into looking into it, these were made in Beepbox.
You can use beepbox in your browser by going to
https://beepbox.co
(this is not my project btw)

Bye!
