The makers of PS: 2 have recently unveiled a 10-second promo of the popular song 'Aga Naga', featuring Karthi and Trisha. The first glimpse of the 'Aga Naga' song in PS: 2 has been released, featuring Karthi and Trisha reprising their roles as Vanthiyathevan and Kundavai once again. Sung by Shakthisree Gopalan to the lyrics written by Elango Krishnan, the song did not feature in Ponniyin Selvan: 1. Still, it was teased during the sequence where both characters first meet, thus becoming a love anthem among fans and a huge hit even before its release. The 'Aga Naga' song in PS: 2 gives another phenomenal success and achievement for the A. R. Rahman-Mani Ratnam combo.
