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!" (2010) are described as "cutesy" bubblegum pop; "Gee" also features elements of techno and hip hop, as noted by Abigail Covington from "The A.V. Club". Nevertheless, the group's musical styles have varied widely ever since; Anzhe Zhang from the New York University wrote that despite the fact that Girls' Generation's styles are deemed "mainstream" in South Korea, the group "has grown sonically more experimental."
