Ja Rule had good #'s but look at someone like Nelly who else had great #'s and fell off on his own. Either way Ja Rule, and 50's sound and way of making music aren't the formula that mainstream is using right now. None of them will ever have similar success as they did in the past.
Plus these artists were broken in using radio, and radio doesn't break shyt these days.
50, Ja and Nelly best bet is singles now. But 50 just isn't connecting. 6 Years ago that Eminem and Adam Lavine would of went #1. The song had everything right for it to be a hit. But I agree with your point. This was 50's mistake, he though he would have the mainstream on lock longer than he did. It always goes in cycles.
