'Kpop Demon Hunters' singer-songwriter duets with Andrea Bocelli on tournament anthem 'DNA' before host Mexico beat South Africa 2-0 in a fiery opener Ejae performs at the opening ceremony of the 2026 FIFA World Cup in Mexico City, Friday. (AFP-Yonhap) Ejae, the Korean American singer-songwriter behind "Golden" from Netflix's "KPop Demon Hunters," performed the official 2026 FIFA World Cup anthem "DNA" alongside Italian tenor Andrea Bocelli on Thursday at the tournament's opening ceremony at Estadio Azteca in Mexico City.The performance marked the live debut of the song, which FIFA released Wednesday. French DJ David Guetta and American rapper Megan Thee Stallion also feature on the recording, but were not in attendance.Ejae wrote the anthem's Korean lyrics, including a line she sings near the end of the track about getting back up after falling. In a statement released by FIFA, she said writing in Korean made the project especially meaningful and called representing South Korea on the World Cup stage an honor.The ceremony began shortly before noon in front of a crowd of more than 80,000 — many of them in Mexico's green jerseys — at the stadium hosting a World Cup opener for the first time in 40 years.The show drew on the heritage of the Aztecs, the civilization centered in what is now Mexico City from which the stadium takes its name, with dancers in feathered costumes and performers dressed head to toe in gold carrying oversized golden soccer balls across the field.
