Ejae was listed first among the writers of the Oscar-winning song “Golden.”
“Golden” appears in the Best Original Song results for the 98th Academy Awards, representing the animated film KPop Demon Hunters. The credited songwriting team also included Mark Sonnenblick, Joong Gyu-kwak, Yu Han Lee, Hee Dong Nam, Jeong Hoon Seo, and Teddy Park.
Ejae is the professional name of Kim Eun-jae, a South Korean-American singer, songwriter, and record producer. In the film, Ejae also provided the singing voice for Rumi, one of the fictional girl group Huntrix’s members. That connection can cause a common mix-up: the performers of a song are not always the same people as its credited writers.
The question asks specifically who appeared first in the listed writing credits, not who performed the song or who wrote every part alone. Ejae is therefore the single canonical answer.
