2nd generation · SM Entertainment
ショウジョジダイ / ガールズジェネレーション / 소녀시대
Girls' Generation set the template later girl groups were measured against: clean melodies, wide synchronized dance, and lyrics that reach for something hopeful.
Last updated:
Gee and Genie turned them into a household name, I Got a Boy pushed song structure and video into stranger territory, and a separate Japanese catalogue runs alongside the Korean one.
Start here if you want the second-generation foundation that most later Korean pop still answers to.

Follow a few songs from the starting point to the group's current sound.
Gee MVGee is the song that fixed the group in public memory, and the video shows why the concept travelled so far.
Genie MVGenie holds the signature wide-formation dance and makes a useful comparison against the lighter debut-era material.
I Got a Boy MVI Got a Boy breaks the song into several sections at once and shows the group at its most experimental.1 daesang · 3 awards · 1 No. 1 finish (compiled by KPOP DISCOVER, as of September 17, 2026)

What anchors Girls' Generation is the wide appeal that set the standard for second-generation girl groups, and an ability to keep renewing rather than stay with the established form. SM Entertainment debuted the eight-piece on August 5, 2007 with Into the New World, making an origin still referred to years later for its cool clarity, its group choreography and its hopeful words.
Gee and Genie widened recognition across the whole country, and I Got a Boy showed a willingness to experiment with song structure and visuals. There are many Japanese releases as well, such as Paparazzi and Flower Power, and following them on a shelf apart from the Korean work shows the range.
FOREVER 1 in 2022 is the fifteenth-anniversary reunion and the entrance for reading the group work and the individual careers together. The eight current members and the former member Jessica are kept apart in the data. Gee, then Genie, then I Got a Boy covers the point everyone remembers, the signature group choreography and the experiment.
Editors' take Gee / Genie / I Got a Boy — three songs cover the wide appeal that set a standard for second-generation girl groups and the will to keep renewing, from an SM eight-piece.
No. 22 of 210 groups with recorded activity in Japan (top 10%)
The denominator is the 210 groups, out of 525 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
