Discovering new music?
rosejn: Tryout http://kgnu.org if you want to expand your horizons.  They have a live stream and a back catalog from the last two weeks of shows.  It's a non-profit station in Boulder, Co, and they get hundreds of new CDs a month representing every kind of international music and out-there genre you could imagine.  Jazz and beyond, musica mundi, jam sandwich, reggae blood-lines, old-grass/new-grass, and african roots are some of my favorites.  The morning and afternoon sound alternatives vary a lot, but once you find DJs you like you can track them.  You won't find any top 40 or pop, but you wouldn't have asked this question if that's what you wanted.
