Only idol group with Melon song of the decade with Gee
Only idol group to have a Japanese album certified million (RIAJ) with Girls' Generation (2011)
Highest peak on Gallup Korea for any artist ever (31.5%, combining all age groups in 2010)
Only artist to have the most popular and second most popular song on Gallup Korea not just one year, but two in a row (2009, 2010)
This one I'm not sure:
Only idol group to have a Japanese single track certified million (downloads, RIAJ) with Gee (JPN)
There's more like The Boys being the number one album on Gaon monthly for 3 months in a row, and idk if this thread is also about firsts (first MV with 100 million views, first artist to 100 music show wins, etc)
Damn! Snsd is THAT group! No wonder their peak and respect is like that of no other group.
