20 de Enero is a song by Spanish pop band La Oreja de Van Gogh, long recognised as one of the group's signature romantic tracks. Its title refers to 20 January, so the clip resurfaces every year around that date in birthday messages, anniversary edits and fan tributes. Shared widely as a short audio snippet, it has stayed popular because the melody is immediately recognisable to Spanish-speaking listeners and evokes a specific era of Spanish pop, making it a simple shorthand for nostalgia, affection and celebration.
