Hallelujah

I love this song. http://www.youtube.com/watch?v=T2NEU6Xf7lM
Halelujah. Leonard Cohen wrote it. Here it's performed by 4 Norwegian guys I've never heard of before, I really like the way they sing it.
Here's another version by Sheryl Crow:

And this one by Leonard Cohen: Some of the verses are different in his version but he wrote it so I guess he can change it if he wants to.

Amazing song. If he never did another thing, he could rest on this alone.
