You should check out Outlaw Country on stream 36 and Underground Garage on 26 I think. Talk about great music !
Kinky Friedman, Jean Shepherd, The Flying Burrito Bros., Johnny Cash, inter alia, are the only musicians that are worth listening to, in my opinion.
The only "recent" group that makes music worth listening to is Presidents of the United States.
Well, if I ever get a Sirius, I will :)
