It seems like Square Enix has a thing for popular DJs. After collaborating with Afrojack to create the fishing music for Final Fantasy XV (among a couple other tracks), the company is once again looking to try and make this sort of thing work.
News broke earlier today that it appears Utada Hikaru, the singer who brought us the theme songs to Kingdom Hearts I and Kingdom Hearts II, will be working with American record producers Skrillex and Poo Bear to create the opening theme song to Kingdom Hearts III titled "Face My Fears". This is noted in the ASCAP database entry for the song.
While Skrillex and Poo Bear have a history of working together on several successful singles, we only know Hikaru and Skrillex have corresponded a few times through their respective Twitter accounts. Otherwise, this will apparently mark the first time all three worked together in unison.
The previously released Kingdom Heart III tracks from Utada Hikaru, "Don't Think Twice" and "Chikai", will serve as the game's ending theme for the western and Japanese versions, respectively.
Kingdom Hearts III is scheduled to be released for the PlayStation 4 and Xbox One in Japan on January 25, 2019, and worldwide on January 29, 2019.
Update (9/27/18): Square Enix has confirmed the news via a press release, and has also shared that both "Face My Fears" and "Don't Think Twice" will be released as singles on January 18.
