Timbaland actually made history with Nas with the Nas feature on "Hot Boyz". That had the record for longest running song at #1 on Billboard's Top Rap songs. It was #1 for like 16 weeks. "You Owe Me" still moves a crowd. "You Won't See Me Tonight" should've been a single. I don't know what you're talking about with that one. "To My" from Tim's Bio is crazy too.
The best Swizz produced Nas songs are all on Lost Tapes 2 or unreleased. Everything else is trash. I give you that one.
With Pharrell, they are 2/4. "Popular Thug" is the best Nas song produced by The Neptunes (it's basically a Nas song as it has three verses from him). That Charlie's Angels song was weak as is "BBC" (it's a feature, but bottom tier Jay/Nas collabo). "Vernon Family" is dope.
The Dre tracks that feature Nas on The Firm album are all dope and "Phone Tap" is classic. "Nas Is Coming" is ok and "Hustlers" is cool.
