Outlaw Country used to be one of my favorite stations, and, even though I've kind of moved on to Lithium, it's still one of the most underrated stations imo. I loved the variety of artists (Johnny Cash, Willie Nelson, Steve Earle, John Prine, The Rolling Stones, Neil Young, Todd Snider, Bruce Springsteen, Elvis Presely, hell, I've even heard them play The Beatles on occasion). I know it gets a lot of criticism for its loose definition of what constitutes "outlaw" country, but that's why I enjoy it so much: you never know what to expect.
Oh, and the shows: Hardcore Troubador Radio, Electric Rodeo, The Big Ass Happy Family Jubilee, The Buddy & Jim Show....I could go on and on.
