5 Simple Reasons.
What he Raps about Money, Drugs, Cars etc lacks a lotta Songs with Substance, his Music isn't moving or makes you relate to what he saying.
His catalouge heard every Album and while i can admit Reasonable Doubt was good didn't enjoy any of his Albums they were boring to me and lacked replay value and the fact he made so many poor Albums.
He always gets RnB Singers on many Songs to do the Hook and if you heard 1 Jay Z Song you heard them all 1 dimensional Topics, lack of Substance, Formulatic method of RnB Singer on Hook.
Rappers that make similar Music to him as far as Subject Matter, Style, Topics like Mase, Rick Ross, Fabolous, Camron, T.I. etc are better Musically and have better Albums IMO.
He isn't a good Song Writer in what he says Lyrically, being Deep and putting Emotion in his Music is big weakness for him. And he never been able to craft good Hooks for Hits.
