Singer Shaan, who has sung Hawa aane de -- a track for the forthcoming World Environment Day to create awareness around air pollution -- says music has the power to convey messages in an effective way.

Shaan, who has also composed the song, told IANS: "The whole idea of creating this song is to create awareness towards air pollution. I wouldn't think I am a major influence of sorts, but I'm a creative person. I feel I have a social responsibility and so it stems from there.
