I guess my point is the car is not somewhere to be thinking deeply about making particular comments on someone's song.

If your kids are in the car, it's probably a better example to them to take the time to pay attention to them, not to the recordist of a song.

Now, if you take the time to explain what you find interesting or enjoyable about someone's song to your kids while you are driving, that's worth tons more than the comment back to the poster of the song. You might end up with a reliable drummer and bass player in your future!
