Actor-singer Ayushmann Khurrana got a huge fan following for himself after giving hit track, Pani da rang, but he does not consider himself as a versatile singer. The 28-year-old, who has sung two more tracks, 'Tu hi tu' and 'Saddi gali', says he can be a versatile actor. "I am not a versatile singer. I have a particular texture of voice and can sing a particular kind of songs, but I am more versatile as an actor and again for me singing is more difficult than acting. Music has a set of rules, but acting doesn't," Ayushmann said.He will release his single, O heeriye, under Yash Raj music. It will be out Sep 14.
