Takahito Eguchi on Sonic Lost World Original Soundtrack:
Cutscene - Solitude
This is the music of scene where the voice ends up stopping in the middle of communication from Amy and Knuckles. The change is happening in the planet and finally, nobody’s there. I express such things like sense of isolation, emptiness feeling, and uneasiness of Sonic briefly and simply. I wanted to show the feeling of this pale halftone without expressing the strong emotions “Sad! Scary! Lonely!”
