Galactic Stadium

From the Super Mario Wiki

Galactic Stadium is a default stadium featured in the game Mario Strikers Charged. It, as it's name may suggest, is set on a giant piece of debris from a spaceship, which is hovering in Space. The background has many floating objects. The stadium has no special features besides its electric fence. Unlike most other music tracks in this game, Galactic Stadium has rather peaceful and calm music.
