"Goin' Crazy" is a song by Dizzee Rascal, featuring vocals from English singer-songwriter Robbie Williams.

The song was written and produced by Tim Anderson and Jamin "J-Man" Wilcox, with additional production by Nick Cage, and co-written by Dizzee Rascal.

Dizzee originally had producers Jamin Wilcox and Tim Anderson singing the chorus but the label wanted Robbie Williams as a better business option due to his notoriety.

[3] Robert Copsey of Digital Spy gave the song a mixed review stating: "In short, the answer is an unfortunate yes.

While Rascal raps about dating models and scoring drugs in clubs, Williams admits: "I believe I'm going crazy/ I believe I'm losing my mind," the result a Frankensteinian blend of indie, grime and pop that never quite hits the spot."
