I agree with the others on Pink Floyd, Comfortably Numb... the guitar solo near the end is just phenomenal. Irony is that I almost NEVER listen to Pink Floyd these days, but just like many of the other songs mentioned here - it has a place (at least for me)... expeditious night time driving, cool temps, windows down, and wide open space outside the car. Sitting in traffic around the corner from home, in the heat, windows rolled up, AC going, etc. doesn't add up for the experience. Can't wait for winter here.
