Of all the songs in the world, pick 8. That request is a little unfair to a Guest DJ, but for music nerds — like WFUV's Russ Borris — it's also a fun challenge. And it's made even better by getting to talk music with someone. So 8Track is more than a mixtape. It's a playlist conversation where the songs and segues lead the way. In our 12 episode first season, you'll hear Russ joined by St. Vincent, Jon Batiste and writer Brian Koppelman, plus Weezer, Gail Ann Dorsey, Sleater-Kinney and more. Look for new episodes weekly, starting Thursday, September 23.
