My favorite Rafi number is Dil Ka Bhanwar Kare Pukar Pyaar Ka Raag Suno...
Rafi saaheb to me is the epitome of the Indian romantic with a heart of gold with a voice that could convey a thousand emotions but the romance best. I am yet to find someone who could convey the romance in a person so beautifully and so gently. If Kishore Kumar's voice could convey melancholy to perfection, Rafi saaheb could do the same for romance.
