Neptunes and Dre despite thier different styles..... but rite now im a big neptunes fan

thats a hard one...all 4 are good, but lets see...

Dr. Dre-Real West Coast G-Funk type shit
The Neptunes-Experiment With Alot Of Different Instruments
Just Blaze-Samples Alot Of Soul, Good Club Type Beats
Swizz Beats-Some Strange Shit, Makes Tight Beats Too

On This One, I am Going To Have To Go With...The Good Doctor...D.R.E.

Dre or DJ Premier

outta your list... I'd say Neptunes... though dre still popping shit too

Genius 'commerical' pop-like hip-hop duo. Timbaland and Missy Elliott.

Er, just thought i'd throw that in. And i know Missy hardly touches the beat production.

tru masta and RZA make the best beats .................................................. .................................................. ......................

RJD2, and there is NO question about it. Anyone who disagrees, we can debate.
