Career:

A turning point in Changbin's adolescence marked the beginning of his path to fame. His love for music was sparked by the positive reception he received from the audience after a dance and rap performance at a school festival. He decided to pursue a career in the performing arts as a result of this encounter, and he attended the MU Doctor Dance Vocal Academy to refine his dance and rap talents.

Pre-Debut and 3RACHA:

After over two years of preparation, Changbin secured his place as a trainee when he performed a self-composed rap during an audition for JYP Entertainment in 2016. He formed the hip-hop trio 3RACHA during this period with other trainees Han Ji-sung (J.One) and Bang Chan (CB97). Changbin used the stage moniker SPEARB and helped create the group's unadulterated, self-produced sound by posting mixtapes on SoundCloud such as J:/2017/mixtape (January 2017), 3Days (August 2017), and Horizon (December 2017). These projects laid the foundation for his future success by showcasing his producing skills and lyrical prowess.
Changbin also made a brief appearance, albeit with little screen time, in Mnet's rap competition Show Me the Money 5 in 2016. His official public debut was made possible by the underground success of his pre-debut endeavors with 3RACHA.

Stray Kids and Debut:

Changbin was revealed as a competitor in the survival show Stray Kids, which was launched by JYP Entertainment in October 2017 and included Changbin in the twin roles of "Producer" and "Rap." Changbin was one of the members of Stray Kids, which Bang Chan hand-picked before the show aired, making it unique among K-pop group formations. Changbin's debut as a member of the nine-member lineup was confirmed on December 19, 2017.
On March 25, 2018, Stray Kids made their official debut with the release of the mini-album I Am NOT, which included the lead single "District 9," which 3RACHA co-wrote and produced. Changbin's gritty lyrical verses and production work soon established themselves as a mainstay of the group's experimental sound, which included elements of rock, EDM, and hip-hop. Driven by 3RACHA (Bang Chan, Changbin, and Han), the group's self-producing philosophy set them apart in the K-pop market, garnering them praise from critics and a devoted following known as STAY.

Solo Work and Achievements:

Changbin has demonstrated his versatility through solo initiatives in addition to group activities. Notable releases include "DOODLE" (2022) on the compilation album SKZ-REPLAY, "Streetlight" (with Bang Chan, 2020), and "Cypher" (2020) as part of the SKZ-PLAYER and SKZ-RECORD series, respectively. He wrote and sang "Fly High" for a Samsung Galaxy Z Flip 5 ad in 2023, and he and Kim Chang-wan worked together to rework "8th Grader (Respect Your Dreams)" for the Samsung Galaxy S24 ad in 2024.
Changbin is one of the most prolific K-pop idol composers, with 166 songs filed with the Korea Music Copyright Association (KOMCA) as of October 2024. His influence as a songwriter was demonstrated in February 2023 when he, Bang Chan, and Han were promoted to regular members of KOMCA.

Milestones with Stray Kids

Chart-topping albums like ROCK-STAR (2023, their fourth consecutive Billboard 200 No. 1) and Noeasy (2021, over 1.1 million copies sold) are examples of Stray Kids' success under Changbin's direction. Their avant-garde songs, such "God’s Menu" and "Thunderous," emphasize Changbin’s contribution to the group’s audacious, genre-bending persona.

Background:

Changbin spent his formative years in Yongin, South Korea, before relocating to Uiwang and Seoul. After attending Galmoe Elementary School, he graduated on February 6, 2018, from Bora High School. His love of performing began at a young age; he led his high school dance club and gave performances at school fairs, which stoked his creative aspirations.

Changbin's parents were initially dubious of his musical ambitions and hoped he would choose a more traditional route, such as studying overseas. When he joined JYP Entertainment in 2016, though, their viewpoint changed, and they became his staunchest supporters—more proud of his accomplishments than they may have been of a college degree.
Changbin sees his parents as role models for their love and tenacity, as well as hip-hop legends like Kendrick Lamar and BIGBANG's G-Dragon. A quirky, likable part of his personality is revealed by his love of dark topics, which is demonstrated by his enjoyment of horror films, and his propensity to sleep with Gyu, a plush Munchlax toy.

Family:

Although Changbin keeps his family life private, certain information has come to light. Although her name and personal information are unknown, he has an elder sister. A picture of a humble, industrious family is painted by the fact that his mother works at a tiny grocery business owned by his father in Yongin. Changbin has shown a strong bond with his family, saying that he would rather remain near them even though his parents encouraged him to study overseas.
Changbin's close-knit relationship with his sister was highlighted in a 2023 Nylon Japan interview when he recalled how they used to cry together when their mother left to take out the trash. His work has been strengthened by his family's emotional support, which is demonstrated by their pride in his achievements.
