How EJAE Wrote The Biggest Songs for KPop Demon Hunters

This is hands down one of my favorite interviews we’ve ever done! EJAE is the voice and songwriter behind the music of KPop Demon Hunters, and in this conversation, she takes us inside the early demos and original versions that brought the film’s songs to life. For the first time ever, EJAE breaks down how these songs started, how they evolved, and what it actually takes to go from rough ideas to music that reaches billions. We listen to early versions, talk through creative decisions, and unpack the emotional weight behind writing these songs. But this episode is not just about demos. It’s about her journey of being a trainee, to facing setbacks, to becoming one of the most impactful creative voices in modern music. It's truly amazing how similar EJAE's story is to the character she voices, Rumi. EJAE opens up about doubt, imposter syndrome, persistence, and trusting your instincts even when the path is unclear. This conversation is for YOU if: You’re an artist, songwriter, or producer trying to find your voice You want to hear how songs really start before they become finished records You’ve ever felt stuck, overlooked, or unsure if your work matters You love KPop, film music, and the creative process behind it What hit me most wasn’t just hearing the early demos, it was EJAE’s mindset, her honesty about the long road, the patience it takes, and the belief required to keep going when nothing is guaranteed. This episode reminded me why Behind The Wall began in the first place: to inspire the next generation of creatives. And it was such a surreal experience to know that EJAE was one of the people we inspired through Behind The Wall years ago when she would watch these interviews and now she's on Behind The Wall herself. What a full circle moment! EJAE, thank you for your openness, your generosity, and for trusting me to help share your story even further. I’m incredibly grateful we officially got to go Behind The Wall with you. And thank you to everyone who continues to support this show and help bring these stories to life. I truly believe this episode will inspire the next generation of creatives. 📘 FREE PDF: 15 Lessons from The Greatest Minds in Music → https://nas.io/behindthewall/products... 🧢 Behind The Wall Merch Drop👕 Be one of the first 150 people and get 20% off with code: WALL20 → https://behindthewall.tv/collections/all ⬇️ More of EJAE YouTube:    / @ejaeofficial   Spotify: https://open.spotify.com/artist/0RMJO... 📸 Instagram:   / ejae_k   TikTok:   / ejae_k   ⬇️ More of Daniel 📺 YouTube: / @danielswall 📸 Instagram:   / danielwall   📱 TikTok:   / danielswall   00:00:00 INTRO 00:01:55 Why This is The Most Important Episode of Behind The Wall So Far 00:02:55 EJAE & Daniel Fan-Girling Over Each Other 00:06:11 Songs Written By EJAE 00:07:11 How EJAE Became A K-Pop Trainee 00:09:47 Auditioning for SM Entertainment 00:10:30 What EJAE Did As A K-Pop Trainee 00:12:40 The World of K-Pop Training 00:16:52 EJAE’s Chinese Speech 00:17:42 Why EJAE Committed to 11 Years of K-Pop Training 00:20:05 K-Pop Groups EJAE Trained With 00:21:54 The World of K-Pop Explained 00:26:03 Why Choreography Matters in KPop 00:27:08 How EJAE Almost Debuted Before Getting Dropped 00:29:38 EJAE Learns To Produce At A Cafe 00:31:52 What SM Looks For in a K-Pop Trainee 00:32:35 EJAE Gets Dropped & What That Really Means 00:34:04 “Maybe Hard Work Doesn’t Pay Off” 00:35:50 What EJAE Did After She Was Dropped 00:37:35 How EJAE Got Through Her Depression 00:41:11 How EJAE Accidentally Got Into Songwriting 00:42:37 EJAE Writes Her First Song 00:44:31 Why Songwriting Came Easier to EJAE 00:46:56 The Story of EJAE & Andrew Choi (Rumi & Jinu) 00:49:26 The Talented Songwriters & Producers Behind K-Pop Demon Hunters 00:50:36 How EJAE Became The Main Songwriter of KPop Demon Hunters 00:52:13 The Story of How It’s Done 00:55:58 How It’s Done - EJAE’s First Demo 00:58:14 How It’s Done - EJAE’s Final Demo (Exclusive) 01:03:46 The Story of Your Idol 01:05:52 Why Your Idol is EJAE’s Darkest Song Yet 01:08:55 Your Idol - EJAE’s Final Demo (Exclusive) 01:13:01 How EJAE Created Your Idol’s Intro 01:17:23 The Story of What It Sounds Like 01:21:00 What It Sounds Like - EJAE’s Final Demo (Exclusive) 01:27:42 15 Important Lessons From The Greatest Minds in Music 01:29:06 The Impact of Golden on EJAE and The World 01:30:00 Why Golden Really Comes From EJAE’s Story 01:35:55 How EJAE Knew Golden Would Be A Hit 01:37:52 How To Write Better Melodies As A Songwriter 01:39:34 EJAE’s Dream of Winning A Grammy For Her 11 Year Old Self 01:43:17 KPop Demon Hunters 2 - Pressure, Creativity & Manifestation 01:46:03 EJAE’s Advice for The Next Generation of Creatives 01:48:38 Check Out EJAE’s Original Music 01:49:11 Thanks For Going Behind The Wall with Us EJAE
