As the velvet curtain fell for the first generation K-pop, with all its local aspirations, the light that shone in the late 2000s reshaped the borders of the music industry world over. Even though the decade of the '90s saw the rise of the idols' model in South Korea with H.O.T., S.E.S., and Fin.K.L leading the way, the second generation experienced a major evolution that turned a home product into a unique cultural export business. Agencies stopped relying on Seoul alone and spread their vision to all of Asia before finally winning the West too. It was the time of going global, opening doors to Japanese and Chinese markets for Korean artists, and developing early online platforms to weave the net of a modern-day fanbase. Amid all this revolution in aesthetics and economics, a number of songs not only topped the charts but defined a whole generation of fans and shaped the unchanging archetypes of K-pop.
In order to grasp the extent of the revolution, one needs to look back to 2009, a crucial year when girl groups, marginalized by an idol culture centered on boy bands, finally took the crown in Korean popular culture. It is precisely in this time frame that Girls' Generation launched "Gee", a song that went beyond commercial success and became an all-out national sensation, an event which echoes throughout the years. The music industry saw the rise of an upgraded version where idols not only sang songs, but also occupied television screens and advertisements. "Gee" became the engine behind this era of bubblegum pop and cute aesthetics, demonstrating that femininity, through a powerful visual identity and military accuracy, was able to rule the market and establish an empire.
Gee is an impeccable example of electropop and bubblegum pop with impressive efficiency created by the production duo E-Tribe. This electropop song is based on a bright synthesizer hook and light electronic bass and uses a cyclic structure made to be addictive right from the start. Repetitive and catchy vocal hooks are used as a hypnotic formula, and the lyrics express the simple but sincere and touching innocence of young love with the same honesty.
The character is not in control here; she is actually taken aback by the fact that she has just fallen in love, which is conveyed through the expression of surprise in the form of the track's name. However, what was missed by critics at the moment and proved to be true retrospectively is the genius creation of the modern global visual branding concept that the song represents. What made this song such a massive hit was not only its melody but the perfect symbiosis of the latter with the colored skinny jeans used in the music video and the choreography created specially for TV appearances.
For those who experienced this period, the influence of Gee can almost be considered as sacral. Witness accounts from the period speak of an experience of communion in which a female ensemble managed, for the first time, to unite all social strata of the Korean society and mesmerize foreign observers. Fans from the first hour can easily reminisce about how common this song was to be heard on the streets of Seoul, when everybody played this song, which became the anthem of happiness. The current historical significance of this piece of work is huge: by making Girls' Generation a "national phenomenon", Gee defined the blueprint for the new model of the modern girl band – with its unique image, extremely developed personalities of each member, and viral dances. Without this innovation, which paved the way for entering the Japanese market and proved the commercial feasibility of having women in the business, such modern superstars like TWICE, BLACKPINK, or aespa would simply not exist.
While Girls' Generation was building the pillars of colorful pop music, there was another group breaking away from the notion of the puppet idol to create a totally different image of masculinity and artistry. In 2008, the release of the song Haru Haru by BIGBANG would be fundamental and irredeemable for the second generation of idols. Until that point, the model of the first generation consisted of a clear division between the producing company and the performing idol. Through this song, the members showed that a boy band had the possibility of breaking down these chains to become truly autonomous and credible artists who could build a unique style based on urban culture.
Technically speaking, Haru Haru is an innovative fusion of hip hop, contemporary R&B and melodics pop, set in a dramatic format drawn directly from Korean grand ballads. Composed and arranged with a considerable input from G-Dragon, the song distinguishes itself from the common standard productions of that time period in the way it puts a focus on telling a story and its honest approach. The lyrics depict the heart-wrenching story of a painful break-up, where the main character decides to put up a façade of indifference and endure pain for the sake of the loved one.
The concept of this silent pain is transformed in the legendary music video, which takes the form of an actual short film. Whereas most other music videos satisfied themselves with filming in simple box-like sets or studios, BIGBANG introduced a necessary cinematographic component to the process.
The feeling raised by Haru Haru in fans of the time period has become engraved as an instance of psychological change. They remember themselves feeling deeply affected by the maturity of topics covered in the song and seeing in this unique combination of sharp lyrics and sorrowful singing something that regular pop music lacks. Thanks to this song, the whole society was able to see male groups in a new light, making even their toughest enemies appreciate their natural talent. Today, the influence of Haru Haru is shown through the ability of the largest groups of the third and fourth generations to create freely. Through showing that a huge commercial success can arise thanks to the writing talent of an idol, BIGBANG made it possible for other groups like BTS or SEVENTEEN to create independently.
This quest for excellence and the renaissance of new aesthetic codes would find an immediate resonance in another formation of the same label, as it decided to explore the topic of the male model through the prism of elegance and avant-garde. Also in 2008, the formation SHINee would present its debut single entitled “Replay”. This song rejected any aggressive or hyper-masculine ideas popular at the time to present a sophisticated freshness to the audience. With the debut of SHINee, the formation introduced the idea of a “contemporary band” as well as its relentless pursuit of modern trends in music, fashion, and dancing. “Replay” was not only the debut song but also a statement of aesthetic purpose, a sign of the appearance of a new male image in K-pop.
Speaking of its musicality, Replay is undoubtedly a classic work of modern R&B/urban pop that can be described through the lens of smooth instrumentation, soft bass lines and highly fluid vocal performance where more attention is paid to harmonies rather than to pure strength. As for the lyrics, the song is told from the first person, namely from the position of the young guy who is deeply in love with the older woman and is fascinated with her innocence and eager to be treated seriously. The combination of maturity in terms of the production with such an honest message creates a very intriguing artistic duality. The background of the track shows how hard the agency worked on the launch of this song, with the video being selected for restoration by the YouTube historical preservation program due to the heritage value of this piece based entirely on stage expressiveness.
The fans’ nostalgia with respect to Replay is a vivid one where they feel like they have been there watching the emergence of amazing artists. They describe how surprising it was for them to see how good and precise the dance movements were, together with the flawless live vocals of the group members. The group SHINee showed the world that a group can still be young and sophisticated but at the same time be impeccable and sensitive. Nowadays, Replay can be seen in the fact that today’s K-pop places the biggest importance on live performances and sound experiments. By creating songs such as Lucifer, Sherlock, and View while experimenting with R&B, electro, and funk, the group raised performance art to an entirely new level.
In the wake of increased borders of Korean art, the political necessity of pushing the Hallyu wave over the sea emerged among the pioneers of the industry. This is how Super Junior managed to mark their names in golden letters in the history of Asian culture with the release of Sorry, Sorry in 2009. When social media was in its early days and YouTube had not started to flourish worldwide yet, the band faced the task of turning Korean pop into a mass phenomenon in the region. Sorry, Sorry became the symbol of the first wave of international expansion of the second generation of artists. Thanks to a broad and diverse lineup, active in music as well as in variety shows, Super Junior popularized the idea of the international group.
The musical construction of the Sorry, Sorry song can be described as an excellent example of the combination of dance-pop and electropop with funk elements, written under the supervision of the famous producer Yoo Young-jin. The song is driven by the catchy and repetitive rhythmic pattern made for immediate rooting in the listener’s brain cortex. The minimalist and powerful chorus becomes a channel for conveying the message about simple but confident attraction. However, the actual trick of mass production of Sorry, Sorry, the trick that became the marketing breakthrough, is the unique choreography of the song. It was created in such a way that the song acquired the worldwide body language ignoring the language barriers.
Sorry, Sorry, for all the fan groups worldwide, symbolizes that one point of time when they knew that they belonged to something bigger than themselves and it is their fandom. Testimonials highlight the zeal with which the music video brought people together throughout Southeast Asia, overcoming cultural differences through the shared experience of the song. The legacy of Super Junior right now is that they have created the fandom in the engineering sense of the term. Opening up new markets of Taiwan, China and Philippines, along with forming different sub-groups within the band, the group has shown that K-pop is not just a trend but a cultural identity.
When international ways had been found and industry codes established, the second generation indulged themselves in the complete aesthetic revolution, which was caused by the rejection of traditions and the manifestation of a new feminine force. In 2011, 2NE1 appeared with their song "I Am The Best", which could be used as a detonator in the industry. Previously, most female concepts revolved around either purity, elegance, or even a nice, proper romanticism. With the help of their aggressive, bold image and music inspired from hip-hop culture, 2NE1 offered a completely different approach. "I Am The Best" became a symbol of absolute artistic individuality and gave rise to the new "girl crush" aesthetics – aesthetics of confidence and freedom of expression, as well as rejection of the gender norms imposed by tradition.
Regarding the music itself, "I Am The Best" is an onslaught of electronic dance, rap, and electropop, produced by Teddy Park, the head producer at YG Entertainment. "I Am The Best" features a powerful bass line, aggressive synthesizer sounds, and martial rhythms which make melody impossible. The chorus of the song makes the statement of autonomy and power through lyrics which cannot be perceived only as arrogant, since they are much deeper than that. "I Am The Best" stands out in the history of K-pop for one particular reason, and it is its ability to get through the Korean pop bubble and catch attention of Western media and brands. Used in global ad campaigns and aired on American radio stations long before the emergence of modern global marketing strategies, "I Am The Best" showed the universality of the eccentricity of K-pop.
The effect of “I Am The Best” on its listeners was liberating, especially for women who now had something to express through their own dream of independence. Fans remember the shocking effect their unusual hairstyles, asymmetrical clothes, and unwillingness to submit to the male look had on them. The legacy of this song is embedded in the essence of modern K-pop, which took the idea of a girl crush as its main commercial resource. The international success of BLACKPINK or the defiant spirit of ITZY and XG come from this breach made by 2NE1. They proved that Korean pop can be revolutionary and rebellious at the same time being successful on the international stage.
However, it would be unfair to reduce the wealth of this period to these five works only because there was no shortage of other musical monuments from the second generation capable of taking their place on top of the same pantheon. How could one overlook Mirotic from TVXQ in 2008, considered by many as the benchmark work when it comes to vocal mastery and male seduction? In terms of history, one cannot forget about the shock wave caused by Fantastic Baby from BIGBANG in 2012, the golden bridge built between the second and third generations transforming K-pop into a worldwide electronic rave party. On the other hand, Genie from Girls' Generation mastered the art of visual concepts and geometrical choreographies, whereas Lucifer from SHINee became the unsurpassed masterpiece when it came to synchronization dancing. Finally, the group KARA with its monumental Step made a very glorious page of Hallyu by finally conquering the Japanese market, proving the universal nature of Korean pop.
A closer look at this historic tapestry reveals that the second generation did not just create popular music songs; it shaped the politics, economy, and aesthetics of K-pop itself with its bare hands. Each group added its foundation stone to an edifice which now intrigues the whole world. Girls’ Generation turned the fantasy of the girls group into an unstoppable national phenomenon. BIGBANG freed the industry of chains to lift the idol to the stature of a sovereign artist of his creation. SHINee added rigour and sophistication to the stage performances which became a major art form. Super Junior went through the test of internationalisation and created the formula for the global fandom. Lastly, 2NE1 shattered all stereotypes to show that female K-pop was capable of being audacious, defiant, and avant-garde. It is thanks to the fusion of these creative powers and these timeless hits that Korean pop music crossed the borders of its peninsula to become a universal musical culture ready to conquer the world and write forever the history of its millions of fans.
