50's energy at the time made In Da Club hot. It doesn't matter what the hook was cos PIMP, 21 Questions, If I Cant, Candy Shop, Amusement Park, etc etc were all smashes... so it obviously wasn't down to the choruses. And when 50's energy faded, the numbers dropped off and bottomed out. That's all normal. And he doesn't owe Banks shyt... he put Banks on and made him mills, that's payment enough.
Yayo surprises me more... dude has his momma crib shot up and his man got murked over the Henchmen beef - that was 50's beef which Yayo carried. On some street shyt, you meant to make sure your man straight after that. You telling him to work for it.... but he's been loyal throughout and even got ma dukes and sister shot at for the boss. Damn...
