The A.R Rahman-composed 'Raasaali' is a beautiful intermingling of a budding romance between a man and  a woman in the midst of  hitting the road at full throttle.The song is a breezy setup of a travel journey that leads to some ghastly consequences. Thaamarai's lyrics subtly interweaves the passing of time and the urgency simmering within the two to convey their love for each other.
