No Woman No Cry [Live] is my favorite Bob Marley song, although there is not a single one I dislike. Marley's almost as good as the dead in my opinion.
Too many favorites...
Redemption Song
Could You Be Loved?
Kinky Reggae
Small Axe
Burnin And Lootin'
Lively Up Yourself
Bend Down Low
Sun Is Shining
Trenchtown Rock
..and many more.
