dramas and plays, variety shows appearances, starting personal YouTube channels, and also continuing to release music individually. By 2020, the diversity of their projects has been declared as an ideal example of growth for a veteran girl group. In particular, Yoona, Sooyoung, Yuri and Seohyun have received attention for their growth and diversity as actresses. Moreover, Girls' Generation is also recognized for continuing to support each other despite their solo activities. Artistry Musical styles Girls' Generation's music is predominantly bubblegum pop and electropop. The group's early singles such as "Gee", "Tell Me Your Wish (Genie)" (2009), and "Oh!"

Girls' Generation's 2014 EP, Mr.Mr., features "exciting" R&B sounds with "cool, simple" melodies. AllMusic's Heather Phares also noted inspirations of EDM, hip hop, traditional K-pop sound, and late-1980s europop on the EP, which she labelled "a set of songs that offers something for every kind of Girls' Generation and expands their musical reach." The group's 2015 album Lion Heart brings back their signature bubblegum pop sound; its third single "You Think", however, is a hip hop song that incorporates
