The chant comes from 'My Happy Song' by Super Simple Songs, the popular children's music channel known for simple educational tunes on YouTube. The track's exaggerated happy chorus made it a natural fit for wholesome edits, and short clips of it began circulating as a baby laughing meme style reaction and a celebratory yay for good news moments. Like many kids' songs repurposed online, its over-the-top cheerfulness also fuels ironic memes, keeping the sound in rotation years after its release.
