You need to replace placeholders of MUSIC_PATH and MEMORY_PATH constants to the paths to the music (ogg format) and the memory file with the frames (here it is).
It is my old python project which i translated into C++ using ChatGPT (it wrote the base).
There is not ogg file with music, because I am afraif of copyright, but you can easily take somewhere this audio, rename the file to "bad_apple.ogg" and don`t forget to type the path into the constant.
