Historical. Influential. Groundbreaking. Run-D.M.C.'s debut single is all of the above, and that's probably why Jagged Edge's flip of it for their "Let's Get Married" remix was so successful. That distinction carried the record to No. 1 on the R&B charts; the quartet even scored a guest verse from Reverend Run. —Ernest Baker

Inspiration: Run-D.M.C. "It's Like That" (1983)

Producer: Jam Master Jay, Russell Simmons, Larry Smith
