If you have children, and you spend a lot of time in the car/camper/rv together, you need "road trip music for kids".  We came across a very entertaining music CD called "Moose Tunes For Kids".  The music style is acoustic-folksy featuring the vocals of a singing moose (aka Brent Holmes).  The tunes are very infectious, to the point you'll be singing them in your head long after the CD is done...  Brent has other kid approved CD's that I'm sure are equally enjoyable, which you can find here:
