Me too. For my car, I just make compilations of my favorite cuts by an artist, and play that. I have one by the Byrds I made which I've probably listened to 100 times, others by Spirit, Springsteen, early Steve Miller, etc. I listen to a lot of jazz at home and work, but find rock is what I want to hear in the car, and shorter songs. Just got a car with Sirius/XM after not having it for 6-7 years, so have been listening to that. And they do not serve jazz well at all.
