Leonard Cohen was one of the most fascinating and enigmatic -- if not the most successful -- singer/songwriters of the late '60s. Religious concerns were never too far from Cohen’s thinking and work, even when he was making a name for himself writing songs about love. In 1984, Cohen wrote and recorded “Hallelujah” for his album Various Positions. The song deals with ambiguous topics and there is much debate over Cohen's intentions or messages. Religious themes and sexual lyrics imply that the track deals with the dynamic of a relationship by using a spiritual metaphor, and the tone is often described as depressive or sorrowful. Covers of the song have been performed by everyone from Willie Nelson to The Prayerbabies.
