Cradles was released in 2019 by American singer and producer Sub Urban, born Daniel Virgil Maisonneuve. The track built a following online before breaking wider through TikTok, where its twisted lullaby sound matched edits, cosplay clips and dark humour videos. Its official animated video reinforced the surreal, storybook-gone-wrong image that creators kept borrowing. Short clips from the song continue to circulate on soundboards because the opening mood is instantly identifiable, even out of context, and it still signals a creepy or ironic twist for audiences who know the trend.
