DDD (EXID song)

"DDD" is a song recorded by South Korean girl group EXID for their fourth extended play, Full Moon (2017). The song was released by Banana Culture on November 7, 2017, as the EP's lead single.

Composition
The song was written and produced by Shinsadong Tiger, LE and V!VE. It samples the 2015 song "WTF (Where They From)" by Missy Elliott featuring Pharrell Williams. The song was described by Billboard's Tamar Herman as an electro-pop song, "[k]icking off with a powerful bass beat and wailing synths". She added that the song "begins as a mid-tempo track before a breathy pre-chorus builds into a climactic chorus that's filled with groovy instrumentals and is enhanced by LE’s garbled titular chant". Lyrically, the song "tell[s] the story of a woman demanding the truth from a lover who cheats on her time and time again but trembles in fear before her, as she alternates between reactions ranging from regret to anger to self-blame."

The song debuted at number 9 on the Gaon Digital Chart, on the chart issue dated November 5–11, 2017, with 89,441 downloads sold and 1,819,529 streams.
