After a two-year break from releasing music, Cascada returned with a new single "Run" on 27 January 2017. Horler stated in an interview at the time that they still plan to release singles instead of a full album, and they already have a new song lined up for release. On 20 April 2017, Cascada released "Playground", the official song of the 2017 Ice Hockey World Championship held in Cologne, Germany and Paris, France. Natalie Horler performed the song for the opening ceremony on 4 May 2017.
