Public transportation typically raises blood pressure and anxiety levels more than anything else, but not if you're hopping on the Chicago 'L' train with DJ Cassidy and R. Kelly

The R&B crooner and boater-sporting DJ (who's been the resident turntable titan at the VMAs, Beyoncé & Jay Z's wedding and a party or two thrown by Obama) put their heads and voices together for "Make the World Go Round." This is a Subway performance we'd actually be down for—boombox, vintage disco vibes and all.

Director X is behind the lens on this one, which is perfect timing given how J. Hud's Chi-based banger with Timbaland, "Walk It Out," dropped earlier today, and he directed that one, too. Lots of Chicago love via video today—and plenty of tracks to keep you dancing, even if it involves matchy-matchy outfits.
