In a world where K-pop idols often seem like untouchable superhumans, dancing through laser lights while dodging paparazzi, EJAE emerges as the refreshing underdog who's slaying demons (literally, in her Netflix gig) and egos alike.
At 34, this Korean-American singer-songwriter isn't just riding the wave of KPop: Demon Hunters' massive success; she's the humble heartbeat behind it. With her velvety vocals as Rumi, the half-demon diva, and penning earworms like "Golden" that topped the Billboard Hot 100, EJAE is proving she's the most likeable, down-to-earth up-and-comer in the game. Think of her as the anti-diva: no drama, just pure talent and gratitude.
Let's dive into her story, sprinkled with a dash of fun for all you culture vultures out there.
Born Kim Eun-jae on December 6, 1991, in Seoul, South Korea, EJAE's life reads like a K-drama script with a happy ending. Granddaughter of legendary actor Shin Young-kyun (who starred in hundreds of films, talk about showbiz genes!), she got scouted by SM Entertainment at just 11 years old in 2003. For nearly a decade, she trained rigorously in the cutthroat K-pop machine, dreaming of debuting as an idol. But life threw her a plot twist: she didn't make the cut. "I used to resent K-pop because I couldn't achieve my dream," she admitted in a candid interview, reflecting on those ego-crushing years.
Instead of bitterness, EJAE channeled it into growth, packing her bags for New York University’s Tisch School of the Arts. There, she earned a BFA from the Clive Davis Institute of Recorded Music in 2014, honing her skills in beat-making and songwriting. As she told The Korea Herald, "I learned to think about how a song might translate into choreography or a music video. That perspective has shaped my songwriting ever since."
Her rise to fame is the stuff of animated fairy tales, pun intended. After graduating, EJAE pivoted to behind-the-scenes magic, mentored by producer Andrew Choi. Her big break came in 2017 at an SM songwriting camp, where she co-wrote "Psycho" for Red Velvet, a track that went gold in the US and snagged awards left and right.
From there, she became a go-to songwriter for K-pop heavyweights like Aespa ("Drama" and "Armageddon"), TWICE ("Last Waltz"), LE SSERAFIM ("So Cynical"), and NMIXX ("O.O" and "DICE"). But EJAE stayed humble, treating songwriting as therapy rather than a ego boost. "Some producers in Korea asked me to topline on tracks for fun. My first song ended up being picked up by a well-known artist. That’s when I realized writing wasn’t just something I enjoyed, it was something I needed," she shared with The Korea Herald.
Then came 2025: the year EJAE went from whisper-behind-the-curtain to full-blown spotlight. Signed to Prescription Songs and WME, she joined the KPop: Demon Hunters project early on, initially as a songwriter. Directors Maggie Kang and Chris Appelhans were so blown away by her demos that they cast her as the singing voice for Rumi, the film's protagonist in the fictional girl group HUNTR/X (alongside Audrey Nuna as Mira and REI AMI as Zoey).
The Netflix animated hit, about idols battling demons while sealing mystical barriers, became the platform's most-watched film ever, with a soundtrack that dominated charts. "Golden," co-written with Mark Sonnenblick, hit No. 1 on the Hot 100, earned four Grammy nods (including Song of the Year), and went multi-platinum worldwide. Other bangers like "How It's Done" (which EJAE belted out a sky-high D6 note in) and "What It Sounds Like" followed suit, with the album peaking at No. 2 on the Billboard 200.
