Everyone experiences music differently. That's the beauty of it. Is Muddy Waters going to tell us how to interpret his blues? I don't think so...
D. Boone thinks its laid-back, so it's laid-back for him. His truth. IMO he is laid back too, but a bit more poppy than daddy. And like RK said, not the real stuff, but that's for all to see, Ziggy even admits that Standup guy.
But he's real cool, he doesn't feel a lot of pressure to live up to his dad, which is damn near impossible, right? Damien might feel that pressure a bit more, but chose a slight variation of reggae to put his mark on.
And he did!

Anyway, the fact that Ziggy Marley admits to smoking weed is a bit.. well... obvious no?
I'm sure that when Russel Crowe's kid turns thirty he'll admit to drinking like a drainpipe too
