Forever Young (Blackpink song)

"Forever Young" was recorded a year prior to Blackpink's official debut in 2016. An Instagram video from November 15, 2015, resurfaced following the song's official release, capturing the then-unreleased track being played from YG Entertainment's headquarters in Seoul. The person recording originally believed that it was an upcoming song by 2NE1, the agency's only girl group at the time, but expressed doubt as the voices of the singers were different from the members of the group. It was later observed in 2018 that Blackpink members Rosé and Lisa were singing their lines from the first verse.

"Forever Young" was written and produced by Teddy and Future Bounce, and runs for three minutes and fifty-nine seconds. Tamar Herman of Billboard characterized "Forever Young" as a song with a "beachy" vibe rooted in moombahton, where the members proclaim "Blackpink is the revolution" in the lyrics. She also highlighted the inclusion of English-language swear words in the song, which she regarded as an uncommon occurrence in songs by K-pop girl groups. Chase McMullen from The 405 noted the track's influences from reggaeton and balaeric beat. A Japanese-language version of "Forever Young" was included in the group's first compilation album release in Japan, titled Blackpink in Your Area, which was first made available through YGEX on November 23, 2018.

"Forever Young" was met with generally positive reviews from music critics. Chase McMullen from The 405 wrote that although "YG has been holding on to the song for years", "it hardly matters when the groove kicks in" and deemed it the best track from Square Up. Tone Glow placed it at number 11 on their list of the top 50 Korean songs of 2018, noting that "Forever Young" triumphs due to its "vibrant energy", despite its "straightfoward" composition. In 2019, Rhian Daily from NME ranked it as the group's third-best track, commenting that the group embraced the moombahton genre with laser-like house beats and reggaeton rhythms to create a "vibrant and colourful foundation" for a song that celebrates youth. Conversely, Palmer Haasch from Insider felt that while the song is catchy, it lacked a certain connection, resulting in an "ending that was not as satisfying as it could have been."

At year-end award shows, "Forever Young" received a nomination for Artist of the Year – Digital Music (June) at the 8th Gaon Chart Music Awards alongside Square Up's lead single "Ddu-Du Ddu-Du", with the latter winning the award.

The song was commercially successful in South Korea upon the release of Square Up. "Forever Young" peaked at number two on the Gaon Digital Chart during the week of June 23, 2018, with "Ddu-Du Ddu-Du" occupying number one. It also reached the top five in Malaysia and Singapore, and peaked at number four on the US World Digital Song Sales chart. It additionally peaked at number 10 on the New Zealand Hot Singles chart and number 36 on the Billboard Japan Hot 100. The song was certified platinum for download and streaming by the Korea Music Content Association (KMCA), for reaching 2.5 million digital downloads and 100 million streams, respectively. In July 2023, it was certified gold by the Recording Industry Association of Japan (RIAJ) for having surpassed 50 million streams.

To promote "Forever Young", Blackpink premiered it live along with "Ddu-Du Ddu-Du" on the music program Show! Music Core on June 16, 2018. They performed it on Inkigayo for the first time the following day. On June 20, the dance practice video for "Forever Young" was uploaded to Blackpink's official YouTube channel; it garnered over 200 million views on the platform by December 2021. "Forever Young" was featured on the setlist of Japan Arena Tour (2018), In Your Area World Tour (2018–2020), and Born Pink World Tour (2022–2023).

During Blackpink's appearance at the Lotte Duty Free Family Festival on June 24, a staff member abruptly halted the group's performance of "Forever Young" before escorting the members off stage. The group did not return to finish their performance, leaving fans angry and confused. The event organizers soon apologized for the incident. At year-end award ceremonies and festivals, Blackpink performed a medley consisting of "Solo", "Ddu-Du Ddu-Du" and "Forever Young" at the 2018 SBS Gayo Daejeon held on December 25. They made a performance with the song at the 33rd Golden Disc Awards on January 5 and the 8th Gaon Chart Music Awards on January 23, 2019.

In the United States, Blackpink performed "Forever Young" on Good Morning America and Strahan and Sara in February 2019. In April, it was performed during the group's appearance at the 2019 Coachella Festival as a part of their 11-song setlist. In April 2023, Blackpink became the first Korean artist to headline the festival and concluded their performance with "Forever Young", which was set against a backdrop of exploding fireworks.
