remember PD said that it's a tough song so think like-wise
ok now i m going to tell which song it could b n which i would have loved it would have been
Could be--Kaise mujhe or guzarish(from Gajini) although i don't think guzarish is a tough song....
Wished it would have been--Kya yahi pyar hai( it's an old song..don't know from which film..but is highly melodious n romantic) or Khoobsorat hai vo itna(fom ROG) or Mera pehla pehla pyar(from MP3)..
so guys plz give ur choice...waiting for ur replies..đ
