After the release of Earth Sick (2014), her fourth studio album, Oh Land divided her time up for a number of side projects, including the recording of soundtracks Askepot (2016) and Watermusic (2018), and a cover of Denmark's national anthem for the 2018 television series The Rain.

[1][2][3] In 2018, she revealed to Rolling Stone that her then-upcoming album would be released in 2019 and was inspired by several recent events of her personal life, such as the divorce from her husband, her second pregnancy, and relocating back to Denmark.

[3][4] As she began songwriting sessions, Oh Land started to focus on relearning how to play the piano, which resulted in a sound and tonal shift for the album.

[6] The song was released for digital download and streaming in Denmark and the United States on 22 March 2019, through Tusk or Tooth Records.

[14] Of similar nature, Simon Bækgaard from SoundVenue described the song's melody as something one would associate with Sunday High mass.

[17] Lyrically, "Kiss in Songs" features Oh Land describing how her potential love interest is able to communicate with her through music as opposed to just speaking.

[15] Emma Sejersen, a writer for Politiken, enjoyed the song, calling it one of the happiest-sounding tracks on Family Tree.

During the concert, she opened the night with a performance of "Kiss in Songs", followed by fellow album tracks "Sunlight" and "Make My Trouble Beautiful".

He wrote that although the songs were unable to meet the fullness of the performance space, they ended up being some of the highlights of Oh Land's show.
