young jeezy is catchy, but he can't rhyme for shit. he thinks saying the same fucking word at the end of each line is rhyming. here's some examples:
"i used to hit the kitchen lights, cockroaches everywhere /
hit the kitchen lights, and i was moppin' floors everywhere"
^ from "thug motivation 101". first line of the first song on his first album. not very impressive.
"i'm a boss, i got juice like the magazine /
and every day i see feds like the magazine"
^ from "standing ovation". second song on his first album. also not very impressive.
"i see opportunity, i'm a opportunist /
n---- ya heard what i said? i'm a opportunist"
^ from "sky's the limit". fourth song on his first album. once again, very lacking in impressiveness.
and then, even when he does rhyme, he has really weak, basic rhymes.
all in all, he's catchy, and he sort of grows on you, but he's not exactly a very talented rapper.
