"Sonic 3" was the first "Sonic" game composer Jun Senoue worked on. Senoue has composed the music for many "Sonic" games since "Sonic 3D Blast", often with his band Crush 40, which he formed with Hardline vocalist Johnny Gioeli. While the Genesis "Sonic" soundtracks were characterized by electropop, Senoue's scores typically feature funk and rock music. Tomoya Ohtani has been the series' sound director since "Sonic the Hedgehog" in 2006, and was the lead composer for that game, "Sonic Unleashed", "Sonic Colors", "Sonic Lost World", "Sonic Runners", and "Sonic Forces". Ohtani said he attempts to "express through music the greatest features each game has", citing the diverse and energetic score of "Sonic Unleashed" and the more science fiction-style score of "Sonic Colors" as examples"."
