It is one of the biggest buys in the Tamil audio world in recent times. There was a bidding war among audio companies before Sony Music clinched the deal.
The audio of the film will be released in the last week of May, as the film is slated for a June-July release.
Harris- Murgados-Suriya trio had struck gold six years back with the music of Ghajini.
Now industry pundits say that they are likely to repeat the Ghajini magic with 7am Arivu.
