This Friday, the long-awaited documentary Marley will hit theaters and video on-demand outlets everywhere. Directed by Oscar-winning film maker Kevin MacDonald, the groundbreaking movie manages to shed new light on Bob Marley, one of the best-known and most influential superstars in the history of music.

Marley gets down to the nitty gritty, uncovering little-known facts about the forces that drove this boy from the rural village of Nine Mile to become the King of Reggae, and helping us to hear his music with new ears. It's the sort of film that contains so many amazing details that it should probably be watched more than once (especially if you happen to be smoked out the first time you see it on 4/20).

Based on just one advance screening—and a close listen to the film's incredible soundtrack album—we've pulled together the back-stories behind these five Marley classics. Let's just say the movie may change the way you hear these songs forever...
