Usher's "Confessions Pt. 2 (Remix)" (2004)
Producer: Jermaine Dupri
Wrapping up a verse about a rich friend who gets trapped by a scheming gold-digger, Kanye raps, "Every time a nigga's sitting on pay stacks/Things come up from way, way, way back." That last part gets the "I'm trying to sing, but not really trying" treatment.
