Aside from "Natural Mystic" I mentioned earlier ( the Natural Mystic compilation album version/mix is better btw ).

More Bob Marley and the Wailers intro:

"Redemption Song" - Beautiful, simple acoustic guitar intro.
"Buffalo Soldier" - Very fine horn intro.
"Concrete Jungle" - Great buildup, then the whole thing explodes in a cardiac rhythm. Electric!! Check out Babylon by Bus live cd.
"The Heathen" - So mystical. Unfortunately, there's too many guitars in the studio version. On the Exodus Deluxe Edition, there's a better realized live version on the 2nd disc (not the same version on Babylon by Bus). Wooo!!
