"I didn't want to be stuck in a rut, so I named the album '2'—a special number with significance for us [(G)I-dle]. When flipped, it becomes 5, representing our five members, and coincidentally, it mirrors our debut date on May 2nd. Additionally, I wanted to create aregular album because of the abundance of songs we had. It wasn't a difficult decision, as regular albums tend to showcase a more diverse side of our music."
—Soyeon explained the name and concept of the album during an interview with "Noon Hope Song," viaSports Chosun.[14]
In an interview withBillboard, the group discussed their creative process. Minnie shared, "I started working on our songs when we were heading towards the end of our world tour (I Am Free-ty World Tour). Although I did not have enough time, I worked on the songs non-stop and was able to make 'Vision' and '7Days' within 10 days." Shuhua added, "Whenever we had a free moment, we practiced and recorded our songs."[2] As noted byBillboard, "all members took active roles in shaping the album's direction," with Soyeon emphasized the collaborative effort, saying, "We all were involved together. We communicated with the choreographer to revise the details while learning the choreography for our title track single 'Super Lady' because I wanted to do something that wasn't so obvious." Yuqi added, "Most of the choreography and concept were centered around Soyeon, as she is the producer of the group, but all of our members gathered together to share our opinions."[2]
2 contains eight tracks. The third track "Doll" was described as a song with "dark atmosphere" with lyrics "providing a fresh shock [in contrast] to the title reminiscent of a cute doll".[15] In her review, Gladys Yeo ofNME observed that "Doll" carries the essence of a sequel to 2022's "Sculpture," from their EPI LOVE (2022), portraying a shift into a villainous arc where the characters are no longer willing to contort themselves to gain love's validation.[16] The fourth track "Vision" is a alluringjersey club song,[16] with "dreamychords."[15] The fifth track "7 Days" contains "emotional guitar riff". The sixth track "Fate" was described as a song with "colorful band rhythm and melody". The seventh track "Rollie" was described as ahip-hop song with "dynamic and vintage" rhythm.[15] The last track "Wife" was described asbubblegum bass-basedpop song with "bold" lyrics that "attracts attention with metaphorical but explicit".[17]
Gladys Yeo ofNME emphasized the versatility displayed in2, noting a spectrum of tracks from energetic anthems to introspective love songs. She commended the album for its diversity and the group's evolving dynamics. However, Yeo criticized certain tracks for their lack of innovation. Overall, she highlighted how the album stands as a testament to (G)I-DLE's individuality both as performers and producers.[16]IZM's Jang Jun-hwan reflects on (G)I-DLE's albumI Never Die, which revitalizes the group's image as resilient and unyielding. He discusses the strategic approach of the pre-release single 'Wife', praising its boldness in breaking taboos within the K-pop scene. However, Jun-hwan criticizes the track 'Super lady' for losing its purpose and succumbing to overproduction. He evaluates other tracks like 'Revenge' and 'Doll', noting their thematic consistency but lack of individual power compared to previous b-side songs. Jun-hwan highlights 'Fate' as a standout track for its lyricism and atmospheric qualities. Ultimately, he questions the album's coherence and differentiation from the group's previous work, leaving lingering uncertainties about its intent and direction.[18]
2 has surpassed the previous record set byI Feel; selling over 1,163,395 copies. Remarkably, the album achieved million-seller status within two days of its release, a notable feat given the recent downward trend in K-pop idol group sales. Positioning (G)I-DLE as the 5th highest-ranking K-pop girl group for all-time initial release sales, trailing behind Aespa, New Jeans, Ive, and Blackpink.[19]
