I generally listen to:
21 - Alt Nation (alt rock)
22 - First Wave ("classic" alt rock)
28 - Faction (rock, punk, & misc)
147 - Raw Dog (uncensored comedy)
73 - Swing Street (big band & swing)
I'm also a big-time channel flipper and just surf through 60 or so music streams for something that catches my ear. I'll listen to just about anything except Country Music.
