You can download story machine's MP3 nursery rhyme from any website, connect story machine with the USB port on the computer with the USB cable in the box (it is recommended to plug it into the USB port integrated on the motherboard behind the computer), and wait 10 second for the computer to install the newly discovered hardware.

Open my computer icon on the desktop-find the removable disk-according to the model of story machine (some contents are different)-and finally put the MP3 file you downloaded into the corresponding folder.
