SM Entertainment confirmed on April 27th that Taeyeon will finally release her song “Happy” on May 4, almost two months after its initially scheduled release on March 9, also her birthday.
The postponement came after the sudden passing of her father on March 9, thus, giving time the singer to recuperate.
“Happy” is an R&B pop song that is a mix of old-school and modern sounds. -HallyuLife.com
