The reggae scene does seem to operate different imo. I'm friends with a couple local reggae bands that have played with those guys and from what i've heard them say about those dudes is that they are the real deal. There is a new wave coming in reggae and it's getting stronger with bands like SOJA, Iration, Fortunate Youth, The Approach, Mighty High, Ethan Tucker, Seedless, Natural Vibrations...etc. The roots of reggae are really coming out in these groups and it's invigorating to hear fresh music like this. It's the fan base that blasted them to number 1. They do alot of self-promoting as do most reggae bands and it's because their music is so sick that they've achieved that spot. I say well deserved.
