The word "Marikolunthu" itself may be a playful corruption of Mani Kolunthu (bell-like beads) or a reference to a local dance step. Regardless, the song acts as a bridge between the older generation (who love authentic folk) and the youth (who enjoy fast-paced beats).
The song is available with visuals from the film Kanninum Kannaadikkum on YouTube via Millennium Audios. Marikolunthu Malayalam Songs Download
