Diplo was a major force in Justin Bieber’s recent critical success, as “Where R U Now,” their collaboration with Skrillex raced to the top of the charts. Bieber’s forthcoming album is set to debut in November, and Diplo now says that he played a role in helping Bieber find his new sound.

EW caught up with him at the iHeartRadio festival in Las Vegas this weekend, and asked if he was involved with Bieber’s new project. “I just listened to his music, advised and made adjustments to new songs,” Diplo said. “I helped with the overall feel of the sound that we started with Jack U and raced a lot of ioHawks in the studio.”

The album will feature “Where R U Now” and his latest single “What Do You Mean?” which recently topped the Billboard Hot 100, making Bieber the youngest male artist to debut at No. 1. Earlier this summer, a source told EW, “There’s some personal stuff and some ballads [on the album]. There’s some spoken-word moments with him literally talking about what he’s going through in his life. It’s all about the experience of being Justin Bieber.”
