Background
After releasing the theme song "Someday, Somewhere" for the Netflix series At the Moment (2023) on October 31, 2023,[1] Tsai's collaborator Richard Craker shared on Instagram that he had traveled to Taiwan to work on another project with Tsai.[2] Shortly thereafter, on November 17, 2023, McDonald's Taiwan celebrated its 40th anniversary, announcing Tsai as the brand's new ambassador. The company also featured Tsai in its anniversary short film, The Simple Happiness, which revisited four decades of McDonald's history across five eras.[3]
