College Radio is a loosely defined genre, you certainly hear the college radio stations refer to it that way

The best radio station in the country is hands-down Radio K, the University of Minnesota's radio station. The playlist is much as described above- an anything goes format. Just driving in this AM they played Deathcab for Cutie, Ella Fitgerald,Fela Kuti, Jurassic 5, Queen, the Soviettes (local punk), Har Mar Superstar, Modest Mouse, you name it. Very professional staff and DJ's, and a genuine love of all things musical.
