This.
The fact that The Trackmasters had like 5-6 songs on the album is really what brought on "the Nas went Pop" backlash. This still plagues Nas to this day, which is where the "Nas can't pick beats" crowd gets its ammo. What they are really saying is "Nas isn't working with the producers I want/wish him to work with". Salaam Remi was called trash as if "Made You Look" and "Get Down" weren't on the same album or he didn't do "What Goes Around" or didn't produce the best songs on Street's Disciple. L.E.S. caught heat as well as if the songs he produced weren't better than the bigger names on Hip Hop Is Dead or that he wasn't also apart of the lineup for Illmatic and provided Nas with heat throughout his career.
Nah purists were mad about the lack of boom bap beats on IWW. The samples were more diverse, the drums were weaker...it's not surprising some people were mad. Hearing Nas working with R Kelly and Jojo was too much. All that being said it's a dope album regardless and has aged better than most 90s albums.
In terms of the beats after that nah. It has nothing to do with demanding Nas work with Premier, and everything to do with wondering why nearly each album featured wack beats that didn't fit his strengths. LES and Dame Grease laced him with weak tracks on I Am and especially Nastradamus. Even Stillmatic had some beats that just make you wonder why the fukk.
He had the budgets and clout to work with whoever he wanted. Not just while on Columbia...the Def Jam albums feature some questionable beats too. This became a thing mainly because Jay Z was rapping over Kanye, Just Blaze, and Bink beats. Hov built a production super team. I will always feel like Nas should have tried to do the same thing. For awhile it seemed like he wanted to start it with Alchemist. I wish he did...
