His style of music ranges from R&B to mellow, chill tracks that perfectly fit the Gen Z bedroom pop genres. Milky got his breakthrough in the lo-fi and K-indie scene after he collaborated with Frad and Hayne (on various songs), who are both lo-fi artists. He also collaborated with Elijah Lee, a fellow Korean living in New Zealand, on "How You Been" and "Paradise," which all did well on streaming platforms.
His other collaborations also gained a lot of traction on streaming platforms, such as "Youuu" with Gareth T. and a couple of tracks with Jimmy Brown, a famous R&B artist.
Milky also has his popular tracks in his pocket, including "You'll Be Alright" and "Take it Slow," which gained 47 million combined streams on Spotify alone.
