2. Just Blaze
No producer has released more tracks with Jay-Z than Just Blaze. After contributing five respectable tracks to Hov’s The Dynasty: Roc La Familia in 2000, the New Jersey-bred beat wizard validated his moniker with game-changing production on Jigga’s The Blueprint the following year. The LP showcased Just’s unique ability to effortlessly juggle soulful soundbeds (“Song Cry”) with hard-hitting neck-breakers (“U Don’t Know”). Just and Hov's chemistry resulted in heaters on four out of five of the God MC's albums over the next decade. Though The Blueprint 2: The Gift and the Curse turned out to be a disappointing follow up, it did produce Just's "Hovi Baby." Blaze is also responsible for "Public Service Announcement," one of Jay's most memorable tracks to date—off his supposed curtain call, The Black Album. "Show Me What You Got" (Kingdom Come) and "Ignorant Shit" (American Gangster) also come to mind when Jay and Just standouts are discussed. Though they haven't released material together in nearly four years, this pair is sure to add to its already impressive list of bangers soon enough.—XXL Staff
