Twelve years is an extraordinarily long time to remain culturally and commercially relevant in pop music, something Justin Bieber has managed to accomplish since his arrival with My World in 2009. Tastes change, trends change, and—for better or for worse—the people surrounding a superstar’s accent to music royalty change. That being said, exceptions persist. One of those exceptions is Bieber’s long-time DJ and friend Taylor James, who has been around from the start of it all. More specifically, he’s been around since Bieber’s second show ever. Hired by Bieber’s manager and music mogul Scooter Braun, James was initially called up because of his experience in the college party scene. The professional partnership eventually turned personal. James has since DJ’d all of Bieber’s birthdays and even Justin and Hailey’s wedding celebration. || James Haidak
