That's the best version of Hallelujah, but I really like the Rufus Wainwright version as well, the one used in Shrek.
And it was expertly used in Watchmen, this version by Leonard Cohen, during the Night Owl and Silk Spectre love scene.
I honestly think I may like Rufus' version the best (although it varies), but it doesn't come off as sad to me for some reason?
