What changes would you make?

This is my top 25 best producers list, but I honestly don't know that much about producers, since rappers get all of the fame. Anyway, what changes would you make to my top 25 producers of all time? I don't completely agree with it, but I'm not sure what to change about it.

Best Producers?

02. Pete Rock

Whoops there shouldn't be 2 Just Blazes lol

I'd like to see Mannie Fresh up there. He's overlooked most of the time, and he's been doing his thing since the early 90's

I would only replace one of the Just Blazes with Cool & Dre, but overall dat list is straight up..

kanya and the neptunes is the best out there since they been with lupe

uh take Diddy off.....you got Just Blaze on there twice in a row lol
