“The Worst Country Song Of All Time” is a tongue-in-cheek song where Brantley Gilbert teams up with the likes of Hardy and Toby Keith to trash country music stereotypes and clichés while simultaneously praising stereotypes of city life. The song also takes jabs at political figures such as Russian President, Vladimir Putin and North Koren leader, Kim Jong-Un.
The song was written by Brantley Gilbert, HARDY, Hunter Phelps, and Will Weatherly. It is the first song Gilbert has written with any of the other songwriters. When talking about the writing process for the track, Gilbert said,

As songwriters, we have a group of people that we’re extremely comfortable writing with and we usually already know what kind of song we’re gonna write. But I branched out and wrote with some folks that I haven’t written with before – and this song came out of one of the first times I wrote with Hardy, Hunter and Will. I’m just really stoked that I met those guys and have had the privilege and honor of working with them."

The collaboration with Toby Keith was decided by both Gilbert and HARDY together. Gilbert said in an interview with Taste of Country Nights,

We felt like we needed an old-school vet with the stamp of approval… I think having Toby on it makes it semi-okay. It doesn’t feel like country music blasphemy quite yet."
