Nah. Love Clark Kent as a producer, but two joints ("Cashmere Thoughts" and "BK Finest"). Bink has the joints on Blueprint and Dynasty. Premo has "D'Evils", "Bring It On", "Friend or Foe". "Friend or Foe '98" m, ", "A Million And One Questions/Rhyme No More", "So Ghetto". I feel he has more legendary songs with Timbaland than Clark Kent, Premo, and Bink. Premo has more legendary tracks with Nas than Jay.
Just Blaze and Kanye? Yes. There's a case there. "PSA" and "Takeover" are just as big as any single Timbaland did for Jay and those songs were never really singles, but felt like it. They also produced some of Jay's biggest singles.
