He's a biter pure and simple.
He bit Big Daddy Kane, Jaz O, Notorious BIG. . .
It's one thing to do it once or twice, but all the time like he does?
Secondly, he's washed up as an MC. He can still rap, but he's no where near as good as he could be.
Thirdly, he sold out for the money. He admits to it on the Black Album.
Jay-Z isn't nearly as influential as you think.
I think the biggest reason people hate Jay-Z is because of you and others like you.
I'm gonna break down why he's not great according to the reasons you gave.
1) Popularity has nothing to do with skills. If that were true, Lil Wayne would be better then Rakim.
2) Who cares about Madison Square, they only gave him that spot because they knew he could sell tickets
3) What's Glastonbury? Honestly, who cares? It just means people who have no idea about rap, headlined him, and his fans from England bought the tickets
4) Fu*k the Royal Family. Again, how does that make him any better a musician/rapper/producer
5) Pop culture has nothing to do with rap or rapping ability. Neither do Lincoln Park
6) The Beatles might have good music, but they single handedly destroyed rock (overly commercialized it), just as Jay-Z is doing now
7) Grammies? Really? So your saying Lil Wayne is better than Tupac?
8) First of all, nothing is wrong with writing rhymes. Secondly Lil Wayne don't write sh*t either. Thirdly DMX doesn't write, and rhymes better than either one. Writing rhymes just proves you care about what you're doing and are willing to take time to perfect your craft
9) Jay-Z hasn't fast-rapped since '94 when he dumbed his lyrics down and sold out. Big Daddy Kane, Kool G Rap and Jaz-O all did it before him and Bone Thugs, Twista, and Tech N9ne do it better
10) No. Jay-Z approached $1 Billion using business skills, there's a difference
11) Again with the popularity contests
12) Percee P and Kool G Rap are FAR more consistent. Jay-Z used to be variable as ever and is now just boring
13) How does hustlin have anything to do with rappin ability?
