## Composition
### Songs

The opening track "Ddu-Du Ddu-Du" is a "fierce" hip-hop and pop rap song with bubblegum pop sound and trap beat. It combines instrumentations of oriental percussion rhythms and whistling on top of the bassline. Lyrically, the song is an anthem about the group's success and self-confidence, based around the hook of "Hit you with that ddu-du ddu-du du". The second track "Forever Young" is a mid-tempo "beachy", moombahton-based dance track with "lasering" house beats and reggaeton swing. The lyrics talk about how they celebrate making the most of your youth, while saying "Blackpink is the revolution". The third track "Really" is a "chill" hip-pop and R&B song about pleading with a lover to show him how much they care. The closing track "See U Later" is a "cutting breakup" dance-pop song that mixes pop and hip-hop with a "trap-laden" chorus, "reminiscent" guitar sound and the distortion 808 bass.
