Music and the children

I saw that my first dranddaughter Tanishka was very much fond of music and she used to listen for more than hour to santoor, fluit and sanai. I tried the same method with Nikita and see the results. She gets excited when the music starts and she has her choices and she complains when she does not like anything for example if it is vocal from maillikarjun Mansoor she does not like. She likes Kumargandharva Bhajans, Asha Bhosale, Geeta Dutta. In this videao she is listening to Santoor which she has started lking more recently.
