“Why” is a song recorded by South Korean singer Taeyeon for her second extended play of the same name. It was released as the EP’s second single on June 28, 2016 by S.M. Entertainment.
The song’s lyrics were penned by Jo Yoon-kyung, while its music was composed by LDN Noise, Lauren Dyson, and Rodnae “Chikk” Bell. Musically, as opposed to Taeyeon’s signature balladic styles, “Why” is described as a hybrid of EDM and R&B with elements of tropical house. The track’s lyrics address a desire to escape a suffocating life.
