A Thousand Years was written by Christina Perri and David Hodges and released in 2011 for The Twilight Saga: Breaking Dawn Part 1 soundtrack. Inspired by Edward and Bella's story, the ballad became a major hit and a lasting wedding standard far beyond the film. Its chorus has since circulated widely in fan edits, covers and short clips online, where the opening piano and vocal remain a shorthand for timeless devotion. The song returned for Breaking Dawn Part 2 in a duet version, helping keep it present in romantic playlists.
