Russian seems to work very well as a language for Reggae songs. I don't know why this surprises me, but it does. Maybe every language works well for Reggae songs, I just haven't heard them yet?
There is a band called Addis Abeba, (Аддис Абеба), I would presume named after the Ethiopian capital of Addis Ababa, for the Rastafari revere emperor Haille Sellasie of that nation (formerly called Abyssinia).
Addis Ababa have free songs available at last.fm.
