Naw, they're not just saying shit to get their music sold. They're telling a story. They don't run around claiming to eat babies and kill people and all this shit, they're telling a story from their perspective. Maybe The Game and 50 Cent claim to kill people, but who cares about them wack ass niggas? That's what music is. Telling a story. There are fiction and non-fiction stories. It all depends on how you tell it which will determine if you're a good artist or a shitty one. Take 50 Cent, that fucker talks about killin niggas and robbin people. Does this punk really do that shit?? No, or at least, I don't think he does. You talk as much shit as 50 Cent talks on the streets, and your ass will be in a box in a week. Now look at Brotha Lynch Hung. Now that nigga tells a story, and a damn good one at that. He raps about some nasty shit, but he does it on top of real shit that happens, real life situations. So, where as a rapper will rap about killing the president out of anger (i.e. Immortal Technique) but will never do it, Brotha Lynch Hung will rap about killing and eating his kids, but still, won't do. So does that make either artist better than the other? Not in the slightest, they're both telling a story, and they're just doing it in a different way.
Also, more than 90% of "gangsta rap" is faker than ICP, yet I don't hear anyone complainin about Dr. Dre and Snoop. Meh, and Snoop is the biggest fuckin sell out I've ever seen. If you wanna jump on someone's nuts, jump on his.
