Step into the heart of DAY6 with “INSIDE OUT,” a poignant track from their fourth studio album The DECADE, released on September 5, 2025. As K-pop’s pop-rock trailblazers, DAY6 marks their 10th anniversary with a song that’s raw, introspective, and beautifully vintage. Unlike the soaring energy of “Congratulations” or the anthemic “Zombie,” “INSIDE OUT” strips things down, weaving Sungjin’s emotive vocals, Young K’s poetic lyricism, Wonpil’s delicate keys, and Dowoon’s steady drums into a haunting melody. Fans on X are calling it a soul-stirring reflection of DAY6’s decade-long journey, crafted with Hong Ji-sang’s masterful production.
As the band rocked Goyang Stadium for their anniversary tour, this track emerged as a fan favorite, echoing their emotional bond with My Days. The DECADE’s 10 tracks, including “Dream Bus,” celebrate growth and resilience. Whether you’re a longtime fan or new to their sound, “INSIDE OUT” will pull you in deep.

Lyrics of INSIDE OUT by DAY6
[Pre-Chorus]
나사 빠진 듯한
말이 안되는 말
내뱉고 있는 나
한심한 걸 알지만, No (I Can’t Stop It)
[Chorus]
Inside Out
표정 하나 숨기지 못해
Upside Down
더는 내가 아닌 듯해
Get It Out
속에 묵혀 둔 말을 꺼내
Time Is Now
가 보자고 Okay
[Post-Chorus]
It’s Love Me, Love Me
날 네 안에 가둬 줘
Please Tell Me You Love Me
평생 날 가져 줘
[Verse 2]
떼 쓰는 아이
같진 않을지
걱정만 한 바가지
[Pre-Chorus]
다 알지 않을까?
말이 필요할까?
막상 하려면 딱
목에 걸려 버리지만 (I Should Say It)
[Chorus]
Inside Out
표정 하나 숨기지 못해
Upside Down
더는 내가 아닌 듯해
Get It Out
속에 묵혀 둔 말을 꺼내
Time Is Now
가 보자고 Okay
[Post-Chorus]
It’s Love Me, Love Me
날 네 안에 가둬 줘
Please Tell Me You Love Me
평생 날 가져 줘
[Bridge]
Say What I Wanna Say, What I Gotta Say
떨림을 이겨내
Do What I Wanna Do, What I Gotta Do
전해 너를 원한다고
[Chorus]
Inside Out
표정 하나 숨기지 못해
Upside Down
더는 내가 아닌 듯해
Get It Out
속에 묵혀 둔 말을 꺼내
Time Is Now
가 보자고 Okay
