I am not Rastafarian, but I too adore the most religious reggae out there.
There has been some criticism of CC lyrics, but it's not the subject matter that is the problem, it's the superficiality of the message when superimposed on the music. Bob Marley sang "Jah live, children yeah!" and it's brilliant. On the opposite side, Social Distortion's "I Was Wrong" is a song a CC artist probably wishes they wrote. I wish I had!
Those tunes come from reality and they connect with listeners, religious or not. It might be enough for a teenager to have an emotional experience, but by the time they are young adults, they will want to reconnect with the outside world. That's the ultimate source of the strength of reggae, the connection between spirituality and social justice.
