If you have young children I would highly recommend the Songs for Saplings CDs by Dana Dirksen. We have the first three volumes of the Questions with Answers CDs (also downloadable from iTunes) and the children love them. The tunes are good and the songs progress through the Westminster Shorter Catechism with lots of Bible verses and great truth as the lyrics.
A few car journeys with these songs playing and children and parents will get to know the Bible better.
