On August 23, 2012, Styles P released the free EP The Diamond Life Project, a collaboration with streetwear/skateboarding label Diamond Supply Co.[1] The mixtape featured guest appearances from French Montana, Pusha T, Curren$y, Trae Tha Truth and Fred the Godson; as well as production from Jahlil Beats, The Beat Bully, Lex Luger, V Don and The Alchemist.

After the release of the EP, Styles continued work on The World's Most Hardest MC Project.

[8] The World's Most Hardest MC Project was met with generally positive reviews from music critics.

[11] David "Rek" Lee of HipHopDX gave the album three and a half stars out of five, saying "Overall, you won't find a highly conceptual track on here but there is enough solid material on here to make a strong case for The World's Most Hardest MC, both in the street and on the mic.

"[10] David Jeffries of AllMusic gave the album three and a half stars out of five, saying "It all works, and there's a winning mix of hardcore and crossover that deserves consideration, but it all runs out too fast, coming off as a taster platter for a better, fatter, four-star Styles P album.
