Into the New World

"Into the New World" is the debut single by South Korean girl group Girls' Generation. Originally written in 2002, it was composed by Kenzie while the lyrics were penned by Kim Jeong-bae. It was first released to digital outlets by SM Entertainment on August 2, 2007, while a CD single was made available several days later. The release includes the B-side tracks "Beginning" and "Perfect for You". "Into the New World" was later included on the group's self-titled debut album, which was released on November 1, 2007.

"Into the New World" peaked at number five on the monthly South Korean album chart in August 2007, and eventually sold over 44,000 copies. Although it only saw moderate success upon its initial release, the song has since been recognized by music critics as a symbolic piece embodying unity and an anthem associated with protest culture in South Korea. Melon and Rolling Stone named it amongst the best K-pop songs of all time.

After its release, Girls' Generation performed "Into the New World" on various domestic music programs. It won Rookie of the Month for August at the Cyworld Digital Music Awards and won a first place trophy on M Countdown on October 11, 2007. Girls' Generation included the song in the set lists for all of their concert tours in Asia; during their Phantasia Tour (2015–2016), the group performed a ballad rendition of "Into the New World".

"Into the New World" was officially released as part of a single album on August 3, 2007. The song was originally first performed by the group in SBS's Inkigayo on August 5, 2007. "Into the New World" reached number one on Mnet's M Countdown on October 11, 2007.

Music video
The music video was filmed from July 21 to 23, 2007, at Paju Book City, Provence Village, Yeoju Promotion Flight School, and Yangjae-dong. The music video was directed by Cheon Hyuk-jin and shows the group members doing various activities. Yoona is designing clothes for a boutique, Taeyeon is flying a light aircraft with Sooyoung accompanying her. In the video, the aircraft Taeyeon flies is broken, and she attempts to repair it, with Sooyoung praying. The aircraft is successfully repaired and both of them are happy. In the last scene of the video, Sooyoung is seen chasing after Taeyeon as she flies away in the aircraft.

Yuri is a barista in the music video and is seen making a latte. Hyoyeon is purchasing a pair of white training shoes at a department store, after which she dances on a stairway. Sunny and Jessica are seen spray painting the worlds "New World 2007". Tiffany is repairing a scooter (specifically, a Yamaha Fino 115) and repaints its body with pink color with flower motif and customizes its license plate. The customized license plate says "Tiffany" with the hanja version of "Girls' Generation" above it. It is actually owned by Shindong of Super Junior. Seohyun is doing ballet while holding a paper plane, on the rooftop of a building.

There are two dance sets featured in the video. The first one is a room with a white background, and the second one is a lobby of a shopping mall. The music video on SM Town's YouTube channel, originally uploaded on June 3, 2011, was remastered in high definition and in 4K and was re-released on January 21, 2022, as part of SM's Remastering Project.

In popular culture
This song is often covered in survival shows, special stages of music charts and award shows. In the first season of Produce 101, it was used as one of the debut song missions, it was also used for the first evaluation in Finding Momoland. Big Mama's Lee Young-Hyun performed a reinterpretation of the song on Immortal Songs - King of Kings annual special feature. At the 2016 Gaon Chart Music Awards, GFriend, I.O.I, Twice and Red Velvet covered the song. In Idol School in 2017, it was used as a preliminary vocal assessment. The nine winners from the show, Fromis 9, performed the song again for M! Countdown 's 600th episode.

After member Jessica left Girls' Generation, the song was also changed into a ballad version for live concert performances. Hyoyeon also admitted on Secret Unnies that the choreography was prepared as far back as a year before Girls' Generation official debut. The ballad version of the song was used as a diagnostics tool in Produce 48. In that cover, Kim Chae-won and Nako Yabuki went on to become members of Iz*One.

Legacy
The song experienced a resurgence in 2016 when Ewha Womans University students sang it during part of their peaceful protest against the university whilst facing 1600 police officers. Girls' Generation member Tiffany responded that

"'As Girls' Generation, it was a proud moment. Right now is the generation for feminists, and it’s an era where messages of women empowering other women are important. I feel like our song played that role, so my heart was happy.'"

Fellow member Yuri also expressed similar sentiments:

"'I saw the video several times, and I even cried because my heart was overcome with emotion. It was a moment when I felt a huge sense of pride as a singer. It was a message that I wanted to deliver through my work, and the inspiration that we wanted to deliver through music and performance was being realized, so it was unlike anything else. At the time when we debuted, I didn’t fully understand the lyrics so I might have been imitating it with bright eyes. But as time passes and I listen to the song, the lyrics touch me even more.'"

During the 2016–2017 South Korean protests, the song, along with Big Bang's "Bang Bang Bang" (2015) and Twice's "Cheer Up" (2016), was sung widely in public squares, leading to it becoming the "morning dew" of the young generation and led to it placing number one on Melon's real-time charts almost ten years after its release. It was also sung in celebration when judges of the Constitutional Court of Korea ruled against the criminalization of abortion in South Korea on April 11, 2019. In 2020, it was used during an anti-government rally as part of the 2020 Thai protests. Some protesters were already aware of the song's usage during protests in Korea. K-pop fans helped translate and memorize meaningful lyrics for protesters to sing along.

In a panel of 35 music critics and professionals organized by newspaper Seoul Shinmun and online portal Melon, "Into the New World" was ranked the 6th best K-pop song of all time; music critic Squib said that it has continuously attracted the attention of the public and has become a "symbol of the times". The Korea Herald also highlighted the song's use in expressing solidarity for a cause, noting that the song's lyrics about unity resonated with Korean millennials. Naming it one of the best K-pop debut songs of all time, Insider wrote "in the 15 years since its release, has become a standard for Korean girl groups".
