Feliz Navidad was written and first recorded by Puerto Rican singer José Feliciano and released in 1970, becoming one of the most recognised Christmas songs in both Spanish and English. Its simple repeating chorus made it easy to remix, and disco and dance versions later circulated online as short clips for the holiday season. The disco arrangement keeps that familiar melody but adds a party rhythm, so creators reuse it every December for memes, edits and festive soundboard posts.
