Jun Senoue on Team Sonic Racing Original Soundtrack:

Doctor’s Mine

A course that runs through the huge mining site that Eggman built to mine the planet. Since this is the final course of the area, I aimed to make the tune more aggressive in a minor key, and Nakamichi’s instrument is now an organ instead of lush piano. In this song, the intro fly-by in particular personally has the feeling of calm before the storm.
