Lupe at his worst is likely so because of delivery or a wack beat. 99% of the time it aint what he's saying though. Lupe's damn near automatic with the verses. Like AZ is
Dont get me wrong, I like AZ. i like Do or Die, A.W.O.L, Aziatic, Pieces of a Man and Format
But he plays it real safe. to the point where some of his shyt is interchangeable. He always has these general street knowledge raps. Nothing wrong with that, but he doesnt stray far from it.
I think it's really wack lyrics along with wack flow/delivery/vocally etc. The lyrics may sound complex but when you actually listen to them and break them down, it's like are they really effective? And often the answer is no. It's not to shyt on Lupe, cause I like him at his best, but often people seem to overhype shyt because of how it sounds rather than what it is.
On his new song he has the bar...
"You're like a contemporary museum of art, that farts"
That isn't good lyrics/lyricism to me, no matter how anyone tries to put it, that shyt is terrible and he often has corny/ineffective pointless lyrics, it's very off putting. I like it when he's focused.
I don't think AZ always brings it lyrically for the most part. Street knowledge is a hugely diverse topic, but he's done all sorts with the storytelling/content etc...
EG:
Ho Happy Jackie
Fan Mail
Never Change
Your World Don't Stop
Street Life
Payback
Having My Baby
Do Me This Way
Good For Nothing
Dead End
Just a few off the top. Plenty of topics, he has the lyric rhyming style, storytelling (which is diverse), street shyt, G shyt, fly shyt. Conceptual, and he always brings it across, throughout his career I think he's been a consistent first rate lyricist. I can't say the same for Lupe who to me has flashes and misses.
