Everyone who has owned a GameCube will probably recognize the iconic startup sound after turning on the system. You can listen to the sound as the blue block rolls around to create the even more iconic logo.

There is even a third hidden startup sound you can hear by holding the "Z" button when you have controllers plugged in to all four slots. Try each one and listen to the sounds inspired by different genres of music.
