If this is your first time hearing this, you are about to experience something so cold, man. Before Jay-Z's Blueprint dropped, cementing Kanye West as an A-list producer, 'Ye was still working with lesser-known artists around Chicago, trying to help get their careers off the ground. One artist in particular was Payroll, a street-oriented artist from the notorious Humboldt Park neighborhood of Chicago. Pay purchased a stellar Kanye-produced track and crafted "Never Change"—an ode to struggle and strife on the mean streets of Chicago. Somehow this track ended up in the hands of Jay-Z, who was smitten with the beat and chorus, and he decided he wanted to keep it for himself. So Pay's "Never Change" became Jay's "Never Change" and appeared on the classic album The Blueprint. Supposedly, Payroll was broken off nicely for his services, but as hood legends go, he wasn't happy with the overall settlement. What ensued after would become known as the "bottle incident," in which Payroll allegedly showed up to a birthday party Kanye and the Go-Getters were chilling at, brandishing a champagne bottle. In the aftermath, well, GLC earned himself a new nickname—"the Knockout King." Hey, it's hearsay! Not saying he's referring to this particular incident, but on "Southside" Kanye does rhyme, "I ain't gotta say it, man, dog, trust me/Bust somebody head, GLC, where was we?"
