If you're an electronic music fan you should add FlyLo FM to that list, Worldwide FM has a couple of good tracks on it too. Personally I mainly listen to Soulwax and FlyLo, but I also dip in and out of Rebel Radio because Johnny Cash - General Lee, East Coast Classics and the soul station (I forget the name) for Marlena Shaw - California Soul. That particular track is excellent for when you're driving along the coast, for obvious reasons.
But, after a total of around 100 hours or so, the radio stations are really starting to wear thin. I sometimes tune into Blaine County FM because I'm pretty sure Danny McBride is on it and he's funny.
