Rosa Pastel was released by Mexican electropop band Belanova on their 2005 album Dulce Beat and became one of the group's best known songs in Spanish speaking pop culture. It found a second life on TikTok in 2023, when users paired its chorus with photos of what they wanted to be as children and clips of their lives now. The format spread because the contrast was funny, personal and easy to copy, and the song has since stayed attached to nostalgic edits about unfulfilled dreams, growing older and accepting change.
