Rogét Chahayed went from learning piano in conservatory to being mentored by Dr. Dre—and his combination of classical fundamentals and 21st-century savvy has made him an in-demand songwriter for hip-hop and pop artists. His shepherding of Jack Harlow’s Come Home The Kids Miss You helped it become one of 2022’s hugest releases; his work on Doja Cat’s “Vegas” and Travis Scott’s “SICKO MODE” propelled those songs to the culture’s forefront.
