I want country music!!

Olivia is loving her new seat in the car.  She has now taken interest in what kind of music there is.  first there were 2 categories- Regular music or her music (Dust, dust, dust, cd).  Well all of a sudden she doesn't want to listen to it.  So now she asks for regular music and specifically country music.  We tried to teach her rock and roll and then also dance (mommy's music).  But now she will say, "I want country music!!!" It is so funny.  I also drove down a street that is not paved/gravel and called it the bumpy road.  Well now all she wants me to do is drive down the bumpy road.  We can't drive down it all the time because we sometimes don't go that way! But she loves it!
