Which is funny, considering how indebted to 'swag' rap from Atlanta Keef is. There's a large part of "Finally Rich" that is celebratory in comparison to the mixtape material, both in the beat selection and in the presentation of Keef. It's still incredibly nihilistic, but more in a giddy sort of 'partying, partying, YEAH!' mood. Though the fact that Keef's parties often involve his friends who are possibly murderers always gives it a more sinister undertone.
Just to illustrate a comparison, since I know that this part of rap isn't so often discussed on Dissensus:

There's obvious sonic differences, both in Keef's vocal tone (his approach is a lot more 'throaty' than the nasal hooks of Roscoe Dash/Rich Kidz/Travis Porter etc.), the much darker approaches of Young Chop, and the greater fondness of mentioning threats against foes in his work. But he's so dependent on this poppier strain of southern rap that never got into critical favor, that I'm amazed that people still think he's just Flocka with less socially redeeming factors. It's not so much a matter of lyrical content, but his whole songwriting approach is MILES from Flocka (early Gucci is actually a much more fitting point of reference. "Kobe" is SUCH a Chicken Talk song.)
