In one discussion somebody had written that they hated YouTube. It certainly has a lot of hateful stuff, but it a great source of music, especially classical, I've found so many things to enjoy there.
This interpretation of Cohen's Hallelujah by Jeff Buckley is one of the most beautiful ones I know. The fact that it is not a religious song in spite of the word does not matter. Christians can still enjoy the wonderful melody and be uplifted by their faith by listening to the word.
