[3][4][5] "Iz U Down" is a club-oriented track that details Ink and Tyga in the club flirting with attractive women that catch their eyes.

Sheldon Pierce of XXL said, it "is a variant of the rap chart ready jingles supplied in such high quantity on the album with the distinct difference being its lower sonic register.

"[9] Chris Thomas of HipHopWired said, "In the opening moments, it's clear that the record has that bounce; the one and the same kind that makes the guy wearing a turtleneck in the club feel himself.

Kid Ink complements the sonics with verses that deliver a straight forward question to women: "is you down?".

"[10] David Jeffries of AllMusic called it the new standard bearer for pop-rap tracks aimed at the strip club.
