Beyoncé recorded Halo for her 2008 album I Am... Sasha Fierce, and it quickly became one of her signature ballads, praised for its soaring vocal and uplifting melody. The opening in particular is instantly recognisable, which helped it travel beyond radio into television performances, wedding playlists and social video edits. Creators now reuse the first seconds to signal love, hope or a long-awaited moment, because the melody carries that meaning without needing lyrics or context. Its familiarity keeps it effective years after release.
