"Dalla Dalla" was written and composed by music production team Galactika (별들의전쟁).[11] It has been described as a lively and upbeat "fusion groove" song that includes elements of popular genres, such asEDM,hip hop,electropop andhouse.[1][2] The members of the group explained that "Dalla Dalla" is a song which is "hard to define, but all the more lovable because of that."[1] The song lyrically weighs on confidence, inspiration and empowerment.[12] "Dalla" (달라) means "different" in Korean, with lyrics including: "I'm different from other kids. Don't try to measure me by your standard. ... I love myself, I'm somewhat different, yeah. I'm different from you."[12]
"Dalla Dalla" received mixed reviews frommusic critics. Tamar Herman ofBillboard called the track an "empowering anthem, introducing ITZY as a group that's an alternative to its peers," as well as "feisty and quick to shift tempos and genres," highlighting its "hip-hop breakdowns" throughout.[2]IZM's Jeong Yeon-kyung stated that: "Dalla Dalla" borrows a dance beat in a ratchet style, exuding aYG atmosphere, and the personality ofRed Velvet andF(x), represented by electronic sounds, comes out. The only choice forJYP style is the old-fashioned 'I'm different' narrative and the 'Gapbunpong (suddenly mood)' chorus, likeMiss A's' "I Don't Need a Man", which eventually leads to the same woman with an arrow of blame."[13] Writing forKotaku, Seung Park judged it to be an "eclectic mashup of a mature version of some ofRed Velvet's more esoteric work withBlackpink or2NE1's hip-hop-esque aesthetic." Park added that the song is a "solid opening bell of what is shaping up to be a long and interesting career."[14]
Taylor Glasby fromDazed ranked it eighth on their list of 2019's best K-pop songs, writing the song "evokes two outlandish 90s moments: the wobbly bass of... "Flat Beat" and the brat-pop of... "Trouble"." She added, "Like the latter, "Dalla Dalla" owes more to its artists' personalities, and despite several coats of K-pop polish, embodies that same scrappy energy and ballsy confidence."[15] In 2020, the lyrics of "Dalla Dalla" were displayed in an exhibition titled "Korean Pop Lyrics: Melodies of Life" at theNational Hangeul Museum in Seoul.[16]
"Dalla Dalla" amassed the top spot on variousmusic programs; it achieved 9 wins including a "triple crown" (or three wins) onInkigayo. Itzy received the Digital Bonsang award at the34th Golden Disc Awards for the song due to its success on digital platforms in South Korea.
