From the Super Mario Wiki
Mute City is a place in the F-Zero series, and it is located on Earth. It also appears in Super Smash Bros. Melee as a stage. Mute City takes place on a large F-Zero race track with a small platform hovering in the middle of it. Occasionally, this platform will go down, exposing the road. F-Zero Racers will sometimes race into the players. This will cause serious damage to the player. If the player falls onto the road while the platform is moving, he or she will be damaged and thrust upwards. Being Captain Falcon's home-stage, most battles involving him are fought here.
It also appears in Adventure Mode where after the player has finished the F-Zero Grand Prix stage, Captain Falcon must be battled. The Super Smash Bros. Melee version of the song appears in the PAL version of Donkey Konga 2.
