Top Hip Hop Producers ...?

I usually tend to stop paying attention after top 10. I'm ok with the top 8. I'd probably rearrange them but overall it's not a bad list. I am not at all a fan of Timbaland, so I think he's ranked way too high. I also think the Neptunes are a bit too high; definitely wouldn't rank them ahead of Prince Paul DJ Quik and Dilla.
