Haru Haru

"Haru Haru" (Korean: 하루하루; Day by Day) is a song by South Korean boy group Big Bang. Released through YG Entertainment on August 8, 2008, as the lead single for their third extended play Stand Up, it became one of their most popular singles and one of South Korea's best-selling songs, besides being regarded as one of the most influential singles to come out of Korean pop music. A Japanese version of the song was included in their third Greatest Hits album The Best of Big Bang (2011) and in the Japanese version of Alive (2012).

Composition
With the release of their first EP Always (2007), BigBang began to incorporate a range of different genre into their music, moving away from their original hip hop roots. Stand Up continued their experimentation. The song was written by G-Dragon, with arrangements provided by Japanese DJ Daishi Dance. Additional Japanese lyrics were written by Shikata, iNoZzi, and Shoko Fujibayashi. "Haru Haru" was described as a combination of a dance song with a hip hop ballad, driven by a sentimental piano melody. The song also includes a synthesizer sound that sounds like an orchestra that feels its "empty spaces". The composition was noted for "weaving in and out of tempos seamlessly" which forced a "a sense of anxiety on the listener." "Haru Haru" deepened the "Big Bang style" of music that had its breakthrough with "Lies." Tamar Herman of Billboard wrote about the track's composition: "The song begins simply enough with a piano tune and breathy vocals until T.O.P's deep bass rap explodes to transform it into a hip-hop ballad like none other. G-Dragon and T.O.P's contrasting rap tones play off one another to offer a sharp change from the passionate vocals of Daesung, Taeyang, and Seungri, while the orchestral accompaniment draws the whole thing to a symphonic peak. Nearly ten years after its release, 'Haru Haru' [sic] is still the epitome of Big Bang's sound."

Critical reception
One of the group's most popular songs, receptions for "Haru Haru" were fairly positive. Billboard hailed the track an "experiential masterpiece" and named it the group's second best song. In a survey involving 30 music industry experts by South Korean magazine Dong-a Ilbo, "Haru Haru" was chosen as one of best male idol songs in the past 20 years. Spinditty felt that the track "has a nostalgic feeling, which conveys the tragic, sad, and deep story behind the song." Sun-Times included "Haru Haru" in their list of the best BigBang songs, calling the track "an enduring anthem for the band."

E. Alex Jung from Vulture called "Haru Haru" "the undisputed song of the decade", commenting on the single's influence, he wrote that the song presented a sound that "was once innovative" but it "has since been copied and standardized to the point where almost every boy band now has a charismatic rapper with a booming voice." Jung concluded that "Haru Haru" "tapped into the Zeitgeist, blending a deep affinity for torch songs with the swagger of hip-hop, and set a wildfire to the K-pop fandom." In 2023, Rolling Stone ranked "Haru Haru" number 7 in their list of the 100 greatest Korean pop songs of all time.
