WRGP, the Florida International University student radio station, broadcasts out of South Miami-Dade and has a fairly weak signal. But it's worth the extra effort to tune in (or visit it online). Along with great reggae programming, the station has the same element that makes many college stations great: music geeks. Full-time straight-up retro-Adidas-wearing, shag-haircut-sporting college kids who want nothing more than to dig through every singles bin in every secondhand store and wade through every free music Website so you don't have to.
