Taxi" and "Let It Rain", were used as the background music for various versions of Girls' Generation's CF with Lipton Tea.

[4] Girls' Generation became the highest earning foreign artist in Japan for the first half of 2011.

James Hadfield writing for the Japan edition of Time Out lauded it as a "cohesive" album and regarded the record as "far better than any of their Korean full-lengths".

[10] Spin's editor Chuck Eddy picked "Bad Girl" as a highlight on the album, calling it "over-the-top" and "Latin-freestyle-emoted" track.

[8] Writing for the same magazine, Charles Aaron ranked Girls' Generation number 18 on Spin's list of 20 Best Pop Albums of 2011; he praised the record as a collection of "over terrifyingly sophisticated dance tracks" and chose "Run Devil Run" as a standout.

[12] An editor for Sputikmusic gave the record a favorable review, remarking that it is a "fairly unusual pop album" in the sense "that it is entirely devoid of filler", but opined that the songs were still a notch below "world class".

[14] The album topped the Oricon Daily Album Chart at first place on June 1 with a sales count of 74,000 copies, which made Girls' Generation the first foreign girl group ever to top the chart on the release date.

[16] One month after the album release, Oricon reported a total sales of 250,000 copies.

[17] This surpassed the previous record of 7th place and 569,530 copies sold by SM Entertainment labelmate TVXQ's Best Selection 2010,[18] and made Girls' Generation the highest selling album by a Korean group on Oricon at the time.

The previous record holder was the original soundtrack for the Korean drama Winter Sonata, which remained in the Top 10 for 16 weeks.

They took second place and were crowned the first ever overseas girl group to reach number 1 on the chart.

On April 20, 2011, the girls added another accomplishment to their belt as the RIAJ (Recording Industry Association of Japan) website updated their charts showing that SNSD's Chaku Uta Full (ringtones) downloads for "Gee" went Double Platinum.

The single also managed to clinch the number 1 spot on Billboard's Japan Hot 100 chart for two consecutive weeks.

Due to overwhelming demand, with up to 300,000 applicants applying for tickets,[33] additional stops were added to the tour.
