I love dancehall and reggaeton music too. I think its reggae just not the political kind we grew up with. This new stuff has a faster tempo its way lighter when it comes to song lyrics. Its more about wooing the girl, having a good time.
As for what Bob would think? He would still be playing his Roots Reggae and be proud of what his influence had a hand in creating.
Thats a good way of putting it. The next generation follows in the previous ones foot steps and add a bit of their own flare, then the generaton after that just takes it to a whole other level. I think its great as long as the real vibe isn't lost.
