"Smile" is a single by Australian recording artist Dami Im, released on 26 May 2015. It was written in Solna, Sweden by Im, Hayley Aitken and Olof Lindskog, and produced by the latter under his production name Ollipop. "Smile" is an upbeat bubblegum pop and doo-wop song that consists of a saxophone rift, electric guitar, synth, handclaps, harmonies and backing vocals. Several critics felt its production was reminiscent of Meghan Trainor's sound. Lyrically, "Smile" conveys a positive message "about loving and appreciating yourself and doing all the simple things in your life to make yourself smile and be ultimately happy." The song received mixed reviews from critics; some complimented its fun pop sound, while others criticised the simple production and Im for following Trainor's sound.
