Joel Klaiman: The 2015 Billboard Power 100
NO. 95

Joel Klaiman

46, Executive vp/GM, Columbia Records

Last year's rank: --

Klaiman, who oversees Columbia's digital, marketing, PR, promotion, licensing and branding divisions -- and still manages to coach his son's travel basketball team -- led the charge on the top two selling songs of 2014: Pharrell Williams' "Happy" and John Legend's "All of Me." He also implemented the label's quick-to-market initiative that made DJ Snake and Lil Jon's "Turn Down for What" one of 2014's best and most-licensed earworms. 

HARDEST BUSINESS LESSON LEARNED: "You can't trust anybody."
