Signal (Twice song)

The song was released on May 15, 2017, by JYP Entertainment and distributed by KT Music, as the lead single from their fourth extended play of the same name.

[2][3][4] In June 2017, Twice released a compilation album titled #Twice which consists of ten songs including both Korean and Japanese-language versions of "Signal".

[1][10][11] Lyrically, it expresses a girl's frustration who keeps sending "signs and signal" to hint her feelings for a guy but is unnoticed.

[17] It has a science fiction-fantasy theme featuring a green-headed alien and the nine members of Twice with their own superpowers: Nayeon's superpower is time reversing, Jeongyeon's is time freezing, Momo's is super speed, Sana's is invisibility, Jihyo's is x-ray vision, Mina's is hypnosis, Dahyun's is self-duplication, Chaeyoung's is telekinesis, and Tzuyu's is super strength.

[19][20][21] "Signal" debuted at number 1 for two consecutive weeks and 4 on Gaon's Digital Chart and Billboard Japan Hot 100, respectively.

At the 2017 Mnet Asian Music Awards, "Signal" won Song of the Year and Best Dance Performance – Female Group.
