You Are My Sunshine is a classic American folk and country song first recorded in 1939 and sung for decades as a gentle lullaby and love song. The demon version is an internet-era remix that pitch-shifts and distorts a vocal performance into a deep, menacing voice, turning comfort into a horror joke. Clips like this spread on short-form video and soundboards because the melody is instantly recognizable even when warped. Creators keep reusing it for haunted dolls, cursed nursery scenes, and ironic edits where something sweet should not sound threatening at all.
