Hallelujah is an interjection from the Hebrew language, used as an expression of gratitude to God. The term is used 24 times in the Hebrew Bible, twice in deuterocanonical books, and four times in the Christian Book of Revelation.

"Hallelujah" is a song written by Canadian singer Leonard Cohen, originally released on his album Various Positions (1984). Achieving little initial success, the song found greater popular acclaim through a new version recorded by John Cale in 1991. Cale's version inspired a 1994 recording by Jeff Buckley that in 2004 was ranked number 259 on Rolling Stone's "the 500 Greatest Songs of All Time".
