## B1A4 and songwriting
Jinyoung debuted on April 23, 2011, performing "O.K" from B1A4's first EP *Let's Fly* on MBC's *Show! Music Core*.[1](https://www.melon.com/artist/detail.htm?artistId=645611) • [4](https://zetawiki.com/wiki/%EC%A7%84%EC%98%81_%281991%EB%85%84%29) Within the group he served as leader and lead vocalist and took charge of shaping its musical identity: he included his own song "Bling Girl" on the debut EP and went on to produce the group's full albums himself.[1](https://www.melon.com/artist/detail.htm?artistId=645611) The March 2012 title track "Baby I'm Sorry", from the first full album, marked the point at which he was seen as having a composing career unusual among idol members.[1](https://www.melon.com/artist/detail.htm?artistId=645611) Korean profile writing describes him as an idol who can handle not only writing and composing but also arranging, background vocals, and vocal guiding, contributing heavily to B1A4's sound.[5](https://seore.org/w/%EC%A7%84%EC%98%81%281991%29?from=%EC%A7%84%EC%98%81%28B1A4%29)
B1A4 released Korean albums through 2024, including *Rollin'* (2017), *Origine* (2020), and *CONNECT* (2024), after debuting in Japan in 2012 with "Beautiful Target".[6](https://www.b1a4-official.jp/posts/discography?category=KOREA)
