Deserving Oscar winning song compositions from our Industry??

My pick is Gango renuka thalli by Devi Sri Prasad...masterful composition,this song doesn't even have lyrics..he just used one word n made a song, excellent song mixing and peak sound quality....

may/or may not win Oscar but thing is we have failed to promote such compositions international wide..music is rangasthalam is one of its kind and was never done before in international cinema as well..when our ppl can appreciate zimmer's work why not rangasthalam music...

Mention ur picks of song compositions which deserve Oscar/international recognition (not ost)
