I was watching the Amul Star Voice of India and the song from Bhhol Bhulaiya: Ami je tomar---Mere Dholana was sung wonderfully by Anushka. The sargam is fantastic. However, the opening tune of the song (Ami je tomar, shudu je tomar) sounds exactly like the song: Tumhe jo bhi dekh lega.

On a different note I recently heard a song composed by Anu Malik which is exactly like a Rafi sahab song from Ek Musafir Ek Hasina: Mujhe dekh kar aapka muskurana, mohhabat nahin hai to phir aur kya hai. I have the song but is of 19kbps. Does any one know the song composed by Anu Mallik?
