Girls' Generation

It took two years to click. 2009's 'Gee' turned bubblegum synth-pop and a deceptively simple four-syllable hook into a phenomenon, topping the domestic charts for nine straight weeks and becoming one of the most-viewed Korean music videos of its era. From there, Girls' Generation became the standard-bearer of K-pop's so-called second generation, expanding into Japan, spinning off sub-units and solo careers, and stringing together hits — 'Genie,' 'Run Devil Run,' 'I Got a Boy' — into the mid-2010s before member departures thinned the lineup. What testimony exists about the group's own formation comes almost entirely from individual members naming individual heroes, not a collective story.
On a March 2009 episode of the KBS game show 1 vs 100, host Son Beom-su asked contestant Taeyeon a blunt question: which singer made her want to become one? She hadn't rehearsed an answer. "보아 선배님보고 자극을 많이 받았다," she said on air — "I was greatly inspired by watching sunbae BoA," using the honorific Korean workplaces reserve for a senior in the same trade. BoA was SM Entertainment's teenage trainee-turned-star since 2000, proof the label's system could work; Taeyeon has named that broadcast, not a private feeling, as literally why she decided to sing.
listen forPlay BoA's 'No.1' against 'Into the New World' and listen for the shared house move: both open with a hard synth-and-brass fanfare before the vocal even lands, then build the chorus around a chanted hook sung in tight unison rather than a lead-and-harmony split — SM's way of turning a crowded roster into one defiant voice. It's the same brief BoA delivered solo in 2002 and Girls' Generation delivered as a nine-piece five years later, at their own debut.
In March 2014, on MBC radio's 2 O'Clock Date, dance-line member Hyoyeon volunteered something more personal than a playlist pick: "이효리는 나의 롤모델이다. 남자친구에게 다가갈 때는 이효리 노래처럼 춤을 추면서 하고 싶다" — "Lee Hyo-ri is my role model. When I approach a boyfriend, I want to do it while dancing like in her songs." Lee, formerly of the girl group Fin.K.L, became South Korea's reigning solo dance-pop star with 2003's '10 Minutes.' Hyoyeon names her for one transferable skill: making choreography read as flirtation, not spectacle.
listen forPlay '10 Minutes' against 'Genie' for the shared trick: a bright, chantable hook engineered to double as a dance cue, delivered in a light, teasing vocal that sells the choreography as flirtation rather than athletic display. Lee built her career-defining single around exactly that register in 2003; six years later, Girls' Generation's own signature dance-break single works the same room — playful, not powerhouse, is the through-line Hyoyeon pointed to.
