Smitten-Downes was discovered for her work on BBC Introducing and was invited to compose a song especially for the 59th Eurovision Song Contest. The song has been described as a powerful, contemporary, anthemic and uplifting track specifically written with live performance in mind. Talking to the BBC she said, "I'm so excited for everyone to hear 'Children of The Universe'. I'm so happy with it. To represent the United Kingdom in such a huge competition, not only as a singer and performer but as a songwriter is an unbelievable honour. I hope I can do us proud". The song was inspired by Max Ehrmann's poem, Desiderata.
