I love "wait, wait, don't tell me". Its not so good to listen in the car though, I laugh so hard that it makes it difficult to drive, and then I have to pee...
We have a local daily show called Eklektikos that I love. All kinds of music, and the guy who hosts it has a truly impressive knowledge of music. He will sometimes follow an idea, or musical link for the whole show. For example, he might play all songs that mention clouds, or a musical link to a Bach peice that is repeated in many different genres of music. KUT Austin.
I car pooled years ago, with a one hour commute each way. We were radio compatible from the start...NPR both ways, whoever was driving.
Gotta go cook dinner and listen to Evening Edition
