Lights

"Lights" is a song recorded by South Korean boy band BTS. It song was released as a double A-side single with the Japanese version of "Boy with Luv" on July 3, 2019, through Universal Music Japan, and was later included in their fourth Japanese-language studio album, Map of the Soul: 7 ~ The Journey ~ (2020). This marked the band's first original Japanese single in two years since 2017's "Crystal Snow". The song was written by Sunny Boy, Yohei, and UTA, with the latter of the three solely handling production. Musically, it is an electropop power ballad in the style of dance music, featuring a bassline and piano-driven chord progression.
