We have about 15 CDs from the series "The 30 best ...". The children's songs on a world tour in addition to the 3 play and movement songs CDs the absolute favorite of our little ones. He runs us practically every day with these 4 CDs afterwards. So it does not pass a day when the land is not one of those CDs in our CD player. I as a parent like the World Travel CD best because it is very abswechslungsreich and you get to hear typical sounds. Hopefully there is a continuation of this world tour CD. If you take some time and explains his child where the individual musical styles are located, one has with this CD nor an educational value.
