A great song from Kirby Super Star. Still not clear on the proper spelling for that.
The very peppy BGM heard in the second stage of both Milkyway Wishes and Meta Knight's Revenge in Kirby Superstar.
Would totally fit a trip through the clouds, a beach, or some other generally athletic/aquatic area.
It might also fit a sky-themed overworld.
In my opinion though, using this for an overworld would be a waste.
But screw me, it's your hack.
