Playback 플레이백 is a four-member female idol group signed under Coridel Entertainment.
Prior to joining Playback, Woolim spent three years as a trainee under JYP Entertainment. She later rose to fame after a video of her appearance on Mnet’s mystery singing show "I Can See Your Voice," where she performed Ariana Grande’s “Problem,” went viral.
Playback released their self-titled debut single album Playback and its title track on June 25, 2015. Just three months later, the group announced they planned to release a new single album on September 2. Their second album's title track, "I Wonder," featured well-known singer and host Eric Nam. The song garnered attention from media due to the involvement of popular Norwegian production team ELEMENT, whose resume includes CeeLo Green, Musiq Soulchild, and Madcon.
