So everybody, everybody (go berserk) Grab your vial, yeah
This is a sample from “The Stroke” by Billy Squier — the song is sampled throughout this track.
The Stroke is a bitter song about the corrupt and greedy music industry destroying artists'careers when they don’t make enough money, that being the only purpose of music. Eminem probably picked the sample partly for that reason, in addition to being one of the most classic old school hip hop beats ever used.
