The group's signature musical styles are characterized as electropop and bubblegum pop, though their sound has varied widely, incorporating various genres including hip hop, R&B, and EDM. In 2017, "Billboard" honoured Girls' Generation as the "Top K-pop Girl Group of the Past Decade". They are the first Asian girl group to achieve five music videos with over 100 million views on YouTube with "Gee", "I Got a Boy", "The Boys", "Mr. Taxi", and "Oh!". In Japan, they became the first non-Japanese girl group to have three number-one albums on the Oricon Albums Chart, and their three Japanese concert tours attracted a record-breaking 550,000 spectators.
