Hallelujah made the list twice. I am rather surprised they picked the Leonard Cohen version as their #1 hit. Maybe they felt they couldn't do otherwise, as he wrote the song. But his version is raw and unvarnished, and lacks the beautiful harmonies of some of the other covers. Too bad he didn't live long enough to see this.

There's a number of these songs I'm not familiar with, so I'll have to give them a listen. I'm also a bit surprised that Ian and Sylvia's "Four Strong Winds" missed the list.
