Cheer Up (song)

A major commercial success, the song topped the Gaon Digital Chart and was the best-performing single of 2016 in South Korea.

They released a compilation album titled #Twice which consists of ten songs including both Korean and Japanese-language versions of "Cheer Up".

[10] "Cheer Up" has lyrics written by Sam Lewis and music by Black Eyed Pilseung, the same team who wrote Twice's hit single "Like Ooh-Ahh" from their debut EP.

It is a dance-pop song that incorporates multiple genres, including hip hop, tropical house, and drum and bass; this blend was described as "color pop".

[13] Tamar Herman of Billboard described "Cheer Up" as an atypical K-pop girl group release that "solidifies Twice's unique style" through its unexpected mix of beats and genres.

[11] Fuse journalists Jason Lipshutz, Tina Xu, and Jeff Benjamin discussed the release in the K-pop-centric podcast K-Stop, describing "Cheer Up" as a 1990s pop throwback reminiscent of Britney Spears' "...Baby One More Time".

They praised the single's fun and catchy tone, rap break, and the "incredible" production quality of its music video but criticized its processed vocals and controversial lyrics, which seem to encourage young women to "play games" (i.e., feign disinterest) with their romantic partners.

[30] It then surpassed 200 million views on August 9, 2017, making Twice the first K-pop girl group with two music videos to reach this milestone.
