You Make My Dreams was released by Daryl Hall and John Oates on their 1980 album Voices and issued as a single in 1981, reaching the top five in the United States. Co-written by Hall, Oates and Sara Allen, the song became one of the duo's defining pop hits. Its profile rose again with the joyful dance sequence in the 2009 film (500) Days of Summer, and later clips and adverts kept the chorus in circulation. Online, creators reuse that instantly recognisable hook whenever a moment needs unmistakable happiness.
