Lude-Poppin' DJ Segues Oval Into Jelly Roll Morton

In Slate, Douglas Wolk has a nice appreciation of college radio. Here's the key passage:

College radio is local and individual, and the digital audio revolution has barely slowed it down. You can download songs from a dorm-mate or someone halfway across the world (or, all right, an actual online music store), but that only works if you already know what you want to hear. The point of college radio is that you get to hear things you didn't already know about.
