The song "Hallelujah" was written by Canadian poet and singer-songwriter Leonard Cohen. He wrote and composed it over a period that took several years, reportedly at least four years and through many drafts of the lyrics. Cohen first released the song on his 1984 album "Various Positions".

Leonard Cohen's version of "Hallelujah" has deep religious and poetic imagery, drawing on biblical stories, and he intended the song to have both a sacred and a secular resonance. The song initially achieved little commercial success but later became famous through cover versions by artists like John Cale and Jeff Buckley, among many others.
