The city of Busan, South Korea enlisted AI-assisted business-to-business marketplace SURF Music to find “thematic, Olympic-style music” to accompany their bid for the World Expo 2023. SURF’s subscription-based marketplace allows artists and music creators to manage their song catalogs via AI song tagging; organize playlists; and submit songs to fit a particular brief. After SURF submitted a playlist of unreleased music to Busan, the city chose “Welcome to World Expo” by Lee Mujin. The partnership will continue through the Expo’s “judgment day” in November 2023.
