Song: "What We Do" (2003)
Album: Philadelphia Freeway

The combination of the crystalline soul beat and Freeway's gruff vocals—along with the ad-libbed assertion that came before it (if he got rocked, this shit was for his kids)—made "What We Do" the perfect storm from the opening bars. Arguably though, it's that concrete-smooth sound of Freeway's sandpaper voice that makes this opener hit so hard, yet sound so smooth.
