Some times we will inspire by some movies and some scenes in our real life. Some times the actor who acted in that movie will also cry by seeing any scene knowing that it is not real. They will connect to some emotional scenes Sometimes. Not only scenes that strength has for songs too.
King Nagarjuna faced this situation when he listened Sahasam swasaga saagipo songs for the first time. Everybody will have anxiety to listen AR Rehman songs. Same nag did the same thing when Naga Chaitanya gave a audio CD to him. Suddenly Amala came into the room and asked why are you crying? After listening Vellipomake song he got tears in his eyes. We will go very far away when we listen this songs. Every song is excellent. He explained how he connected to those songs.
He also felt bad for he missed this song for him. He also shown promotional Jealousy by saying that "AR Rehman gave him tunes only for one movie in my 30 years but he gave 2 movies already to Chaitanya" and proved his happiness as a father.
