Playback released their eponymous debut single album Playback and its title track of the same name on June 25, 2015. Three months later, the group announced they planned to release a new single album on September 2. The album's title track, "I Wonder", featured singer and host Eric Nam. The song garnered attention from media due to the involvement of Norwegian production team ELEMENT, whose resume includes CeeLo Green, Musiq Soulchild, and Madcon.
