Amelia Dimoldenberg, the creator of Chicken Shop Dates, also praised Edwards.
She wrote: “Jamal Edwards, one of the most generous people I have ever met. Someone who loved music and truly believed in all the joy it brings. Going above and beyond to connect people and bring ideas to life.
“You have shaped culture and changed the lives of others – never to be forgotten. Thank you for everything. You will be so greatly missed.”
The official Youtube Twitter account said the industry had “lost a legend”, adding: “Jamal Edwards was an inspiration to so many, supporting artists and shaping culture through @SBTVonline. Sending our condolences to Jamal’s family & community.”
