Green Gold Pictures' upcoming animated film Mighty Raju - Rio Calling launched their song 'Rio Shaher Hai Khushiyon Ka.' This song is beautifully sung by popular singer Sunidhi Chauhan.

The video opens with adventurous Raju, the four year old boy from the city of Aryanagar on a visit to Rio, dancing away to glory with joy to the tunes of the song. The song video also shows a few glimpses of Sunidhi Chauhan in the studio singing 'Rio Shaher Hai Khushiyon Ka'. Sunidhi's voice provides a serene yet enjoyable essence to the song. This song is a bossa nova track, a music genre popularised in the 1950's and 1960's in Brazil: a fusion of jazz and samba. "No one better than Sunidhi who could carry off this style," explains Sunil Kaushik, the music director for Mighty Raju Rio Calling, who recorded this song with Sunidhi. The song perfectly describes Raju's gleeful adventures and how an amazing city Rio is.

Mighty Raju is an Indian animated series of films aimed at young children, focussing on the adventures of Raju, a 4-year-old boy in the city of Aryanagar. The film comes from the makers of Chhota Bheem.
