Artists’ “ancillary” earnings also include the endorsements they clock up, such as producer Mark Ronson and singer Katy B lending their cool to a corporate brand like Coca‑Cola. For that, they will usually be compensated for both the use of their music and of their image. The deals add up: from Lana Del Rey fronting adverts for H&M, to the likes of Jessie J who has got into bed with VitaminWater. (And this from the girl who sang “It’s not about the money, money, money”.)
