Apparently, Dhanush sold the rights of 'Kolaveri di' to a music label for a pittance, without foreseeing the song's astounding success

Kolaveri di might have become a landmark on the 2011 music calendar, but unfortunately, the man behind the popular number - Dhanush - is unable to reap any monetary benefit out of the situation.

Apparently, Dhanush sold the rights for Kolaveri to Sony Music for a pittance, not knowing how far the song was fated to go. And now when there are various versions of the number making their way around the world (in Pakistan, as well), Dhanush's family and friends are dismayed at his meagre income from the deal.

In fact, there is nothing the South star can do to curb the myriad versions of Kolaveri that are floating around. Also, he has no control over the various versions of the song that the actor has served up for future release. Shockingly the Hindi version of Kolaveri is out of Dhanush's hands.

The star-singer says, "I can't release any version of Kolaveri without Sony's approval. And I'll have to share every version of the song with them. So essentially I'll get paid only for my singing. Like the Tamil version, the Hindi version of Kolaveri is with Sony Music. There's nothing I can do about it."

Ask Dhanush why he didn't retain the rights for the song, and he replies, "Who knew the song would go so far? But it's okay. I don't regret it. I am content with what I've got from this song.

And what I've got is priceless." About the song being used for a political campaign in Pakistan, Dhanush says, "The song has crossed a very important boundary." Apparently, plans are afoot for the Tamil star-singer to float his own music company for future Kolaveris.

A collaboration with A R Rahman is also on the cards. The maestro recently singled Dhanush out for praise, referring to him as the Aamir Khan of the South and comparing Kolaveri di to his Aati Kya Khandala.

Responding to Rahman's compliments, Dhanush says, "Coming from him, it's a great honour. I'd love to work with him."
