No need for Python or programming skills to use most scripts (including this one).

A song is made out of a top-level folder track named "Number. The Title" (eg. "04. Sonate in C minor"). Use the "reset" button if modifying song tracks or switching projects while the script is open so that the new songs appear in the list (or just close/reopen it).

I've attached an example of a basic project structure. A project can be structured many different ways depending on its requirements but, at the core–as far as song switcher is concerned, one numbered top-level folder track = one song.
