“That’s a Rack” is one of two promotional singles for Lil Uzi Vert’s album, Eternal Atake, that were released on April 9, 2019. The song’s instrumental is the work of DJ Bangout and Uzi’s frequent collaborator Oogie Mane. It samples “nm_rabbit_2_140.wav,” a loop from Nick Mira’s The People’s Pack loop kit.

This song was originally previewed for less than a minute by Uzi during his set at Power 99’s Powerhouse event held in Philadelphia, PA, on October 26, 2018. He would preview the song once again at Rolling Loud Festival on December 16, 2018.

“That’s a Rack” was leaked online on April 1, 2019, just a day after the leak of “Sanguine Paradise.” The leaking of both songs prompted Uzi to respond in a photo posted to his Instagram story, in which he wrote:

Everytime something leak you know everything takes longer ….so have fun
