Feels like, either Arijit should've been born for this song or the Song should've been born for Arijit Singh. 
The emotions, the peace, the love you feel for this song and feel with this song, listening to Arijit Singh is just awesome. Just awesome. I'm listening to this song for three months now n still it feels so good to listen to it in Arijit's voice time n again.The husky humming in the beginning itself sweeps you away. N' as he starts singing, you fall for it, drown in it and get immersed in it. As he sings everytime, Main tujhko kitna chahata hoon. Ye Tu kabhi sochna sake, feels like saying. yeah! Yeah! I agree! You're absolutely right! How he renders those lines? Wow!!! Amazing Man! What an amazing voice you have? N' what  a music sense you've? Done justice to Mr. Amaal malik's composition n Mr.Kumar's lyrics n what they expected from you. Some songs are born exclusively for someone. Its one such for you Arijit Singh!!
