Mumbai, April 20 : Playback stars Sunidhi Chauhan and Javed Ali have recorded two new tracks, for the web series "Ek Thi Begum". Sunidhi has sung "Rab kyun khafa" and Javed sung "Chaubhati hai tanhaiya". The songs have been composed by Amitraj. Talking about the song "Chaubhati hai tanhaiya", director Sachin Darekar said: "The song talks about the memories that you shared with your loved ones, your closed ones. It's a song that emotes the feeling of love and overlaps it with the hardships and the loss, as well. It's a beautiful song created by Amitraj and sung so well by Javed." On "Rab kyun khafa", he added: " What really touched my heart about this song was its lyrics. It's touching and mournful at the same time and I couldn't imagine anyone but Sunidhi who could bring it to life."
