Whats your definition of a 'wack' rapper?
I think Jeezy is good, he has an instantly recognisable style unique to him, he has has a smooth steady flow, makes tight hooks and spits the kind of lyrics that make rewind the tape, even the corny shit makes me laugh, above all else he makes entertaining music. You cant give a bunch of 'platinum' sounding beats to anyone and expect them to construct a full 19 track album of worth.
Personally i dont need to hear a rapper go so deep and with clever lyrics and metaphor on every track, its bores me to pieces, but its all for debate, to me, this has been by far the best album from a pretty stale year of new rap releases.
