Takahito Eguchi on Sonic Lost World Original Soundtrack:

Cutscene - The Enemy of My Enemy Is…?

As it will become spoiler, I cannot write in detail, but this is the music of the scene of communication of the two teams of Sonic and Eggman who have gotten away from Deadly Six, who have released their powers. I described their hearts’ gradual change from dark clouds to light and until they start to walk towards the one direction together, I made the natural flow by deciding the ending’s fixed tempo.
