Not many songs have been covered by so many artists like Leonard Cohen’s song “Hallelujah.” First recorded in 1984 on the underwhelmingly received Various Positions album, “Hallelujah” received little success upon its release but eventually found fame when Jeff Buckley and John Cale covered the song. However, many people know the song from the Dreamworks’ movie, “Shrek,” covered by Rufus Wainwright.
