Melody Empire Group (MEG) co-produced Planet Blue, a collaborative single between BTS, Coldplay, and South African group Mafikizolo. MEG funded a zero-carbon studio in Iceland for the recording, where the artists blended K-pop, Britpop, and Afro-pop rhythms. The track Blue Horizon features AI-generated choirs and a 24-hour live stream of fans singing along globally. MEG pledged to plant 1 million mangroves per 1 million streams, while proceeds supported Greenpeace’s ocean conservation projects. The single debuted at #1 on 40 country charts and became the most-streamed climate anthem in Spotify history.
