Tomoya Ohtani on Sonic Lost World Original Soundtrack:

Sky Road - Bonus Stage

This is the shortcut-style music fluffily made suitable for the image of a cloud stage in the project’s initial phase, but the stage, where this music seems to be fitting, ended up disappearing due to specification change, and it was about to be shelved once, however a hidden stage had been arranged to be made and it was able to come to light. I think it is a shortcut piece.
