Oscar-winning music composer AR Rahman spoke to NDTV's Rohit Khilnani and explained how important it is to market music in the right way. He feels India lost the opportunity of cashing in on the fever of Indian music when Slumdog Millionaire music was doing well all over the world in 2009. Rahman also said that one should look at South Korea and BTS for the way they market their music. NDTV's BTS Interview airs on NDTV 24X7 on Friday, October 30 at 8:30pm and 10:30pm.
