Im sorry mate thats your opinion I think alot of people would disagree with you. I mean he's multiplatinum all round the world so the sales speak for them self.
And I think alot of his fans including myself would like to see him perform.
If you think he's crap why the hell are you looking at this post. Game is one of the best artists in recent years just listen to 300 bars and you wouldnt question his talent.
