IN生 is Stray Kids' first repackaged album. The album was released on September 14, 2020, and is a repackage of their album GO生. The album contains eight new songs including the leading track “Back Door” as well as all of the tracks on GO生.
Of the new tracks, there are three songs performed by Stray Kids' sub-units — 3RACHA’s “We Go” with Bang Chan, Changbin and Han, DANCERACHA’s “Wow” with Lee Know, Hyunjin, and Felix, as well as VOCALRACHA’s “My Universe” with Seungmin and I.N, featuring Changbin.
The Chinese character ‘生’ has various meanings. There are “live (/laɪv/)”, “life” and “live (/lɪv/)” in English too. So we thought about the sentence ‘Go Live In Life’ and had two titles in mind, GO生 and IN生. Now what I wanted to emphasize was that you have to go “live” in life. On stage, we want to show our true selves and all our aspects that we want to express with such meaning. We thought about this sentence at first thinking that it’d be good in real life too. If we can show what we want to express and show right away in a 生 form without hiding.
