Not Today (BTS song)

"Not Today" is a song recorded by South Korean boy band BTS for their 2017 album You Never Walk Alone, a repackage of their second Korean-language studio album, Wings (2016). The song was written by "Hitman" Bang, RM, Supreme Boi, June, and Pdogg, with the latter of the five also handling production. It was released on February 20, 2017, as the album's second single by Big Hit Entertainment. A Japanese version of the song was recorded and issued on May 10, 2017, through Universal Music Japan, as a B-side of the single album that included tracks "Blood Sweat & Tears" (2016) and "Spring Day" (2017), both also in Japanese. It was subsequently included on the band's third Japanese-language studio album, Face Yourself (2018). "Not Today" is a hip hop and moombahton song which relies on synth-heavy instrumentation. The track's lyrics address themes of injustice, corruption and anti-establishment.

The song received generally favourable reviews from music critics, who praised its energetic sound and lyrical content. Commercially, "Not Today" peaked at number six on South Korea's Gaon Digital Chart and reached number one on the US Billboard World Digital Songs chart. The song also charted at number 23 on the Billboard Japan Hot 100 and number 77 on the Canadian Hot 100.

The music video for the song directed by Sung-wook Kim of GDW was released on February 20, 2017. Inspired by the Lord of the Rings film series, it features the band performing "powerful" choreography with a group of black-clad back-up dancers in the backdrop of rocky valleys. A dance version of the video features close-up and wide-angled shots of the band performing choreography to the song. BTS promoted the song with televised live performances on various South Korean music programs, including M! Countdown, Music Bank, and Inkigayo. It was also included on the set lists of the band's The Wings Tour (2017) and Love Yourself: Speak Yourself World Tour (2019).
