Bob Marley or Geoffrey Oryema. The rhythm helps me stay on the move as I tidy things up and wander around the apartment. When I'm in the basement folding and ironing I like to take down the words to the latest song I'm trying to memorize and sing them. That way when I come up from the depths I not only have a basket of clean folded laundry but also a short song or half a long one in my head.
