[2][3][4] In a 2016 interview with Slim Thug, he claims to have met the album's executive producer, Pharrell Williams, in Houston prior to career a mentorship arranged by Jimmy Iovine, as both acts were signed to the Interscope Geffen A&M Records umbrella at the time.

AllMusic's Andy Kellman praised Slim's delivery for being more charismatic than Lil' Flip and Mike Jones, and the production work from both Mr. Lee and The Neptunes, concluding that "Already Platinum is one of 2005's best rap albums.

"[13] Vibe contributor Rondell Conway wrote that, "Slim's worldly sensibilities make the pensive moments on the album both heartfelt ("Dedicate") and heady ("The Interview").

"[15] Rolling Stone's Christian Hoard called the record "a popwise bastardization of the Houston rap scene's round-the-way charm", praising Slim's "down-home brassiness" delivering "brawny boasts and mesmerizing refrains", and the Neptunes' "arty minimalism" being better than on previous outings.

"[12] Tom Breihan of Pitchfork was critical of most of the tracks by the Neptunes, saying they "lost the gleaming, clattering swagger they once had, relying instead on bloodless synth lines and itchy, nattering drums" and that Slim's performance on them suffered.
