“Forever Young” is the sub-title track on BLACKPINK’s first mini-album SQUARE UP. The track features a dance genre with Moombahton Rhythm, while the lyrics contain the message of “Let’s spend our youth without regret”.

An old Instagram video from 15 November, 2015 resurfaced online showing the song blasting from YG Entertainment’s building in Seoul, South Korea. It was before BLACKPINK even debuted, the fans were surprised since the track was released three years later.

On June 2nd, 2018 BLACKPINK released a dance practice of Forever Young. The video shows the girls dancing while a camera follows each of the members around the practice room.

As a result of the success of the SQUARE UP album, YG Entertainment decided to extend the promotion period until the end of the month with “Forever Young.”
