Don't ask me to remember the channel numbers, but some of my my presets are:
Blues channel (great blues artists spanning the last 50 years)
Deep tracks (they play great tunes rarely heard from the best classic rock bands from the 60s, and 70s)
1940s channel (great channel to hear classic big bands like Duke Ellington, Glenn Miller, Count Basie, etc.)
Jam-On (another great station to hear rare cuts from great bands you don't hear on top 40, like Tower of Power, Phish, The Meters, etc.)
I also bounce over to a few of the harder edge rock too from time to time and catch bands like Sound Garden, and Clutch. I also check out Classic Jazz from time to time.
When I've had my full of music I listen to some of the talk radio stations and catch people like Mark Levin, Bill O'Riley, Ed Shultz.
My wife's car is has Sirius radio and I have it here in my office/studio.
