Nigga got a bad voice. Stop trying to sound loud and work on making sure your flow is right. The words don't mean shit as long as the flow is ill. People only judge words when the flow is only ok or bad. If you have a tight ass flow, it will all come. That's really all he needs work on. How you sound while rapping has to match the song. You can't be loud on a quiet song, or try to stand out over a very melodic song. It just won't flow right. Just quiet down and get better flow. Otherwise, the nigga is bueno.
