Friends were talking about Community, which I haven't seen, and then they started talking about Donald Glover and Childish Gambino and I asked, "Danny Glover is a rapper now?" I've been listening to him intermittently and he's really grown on me plus Mystery Team is entertaining. Also, many musicians/bands invariably sing/rap about how awesome they are so I let it slide unless there is a noticeable fault like lame lyrics or unpleasant beat/sound(example M.I.A.).
