One of my favorite music directors, singers is AR Rahman.
ARR's music is popular in Tamizh and Hindi (he is also popular across the globe and has not restricted himself to film songs).
My three year old has never sat through any Hindi movie with us. We do not speak Hindi at home (only English and Tamizh). But we do listen to Hindi film songs in the van. She sang this yesterday and I happened to catch her on video.. there cannot be a greater tribute to a music director than this. A kid who does not know the language singing fluently .. more Power to his music!!
and here is a link to the original "yeh tara, woh tara".
