NPR has some pretty good shows, when they stay away from politics. "Dr. Zorba," for instance, and "Car Talk." "Wait, Wait...Don't Tell Me" is pretty entertaining, too. And, no commercials.
But, these are all available on podcasts, and so that's how I listen to them.
If I find myself stuck in the car without my MP3 player, I might listen to Dennis Miller if he's on. At least, try to catch bits him on-air between long commercial blocks. But, I cannot stand Beck, and grew tired of Rush ages ago. Caught him slinging too much bullshit. It's 100% Republican 100% of the time. If Republicans came out in favor of killing babies, Rush would find a way to justify it. (And, in the case of the current wars, has.)
Sean Hannity's pressured speech makes him unlistenable. Savage's rantings are designed to make the blood boil. It's one big, long appeal to emotion, and I don't like what it does to my blood pressure. And, I don't care for his thinly disguised racism. His entire shstick is to make angry white males even angrier on their commute home from work.
