I am a die hard Rafi saab fan since my childhood, and I am listening all his songs from then, and I can tell only one thing that you may be any mood, any place, any occasion, Rafi saab’s song are the best, so it really depends on how is your mood, if you are feeling romantic, than the songs of Mahua, Heer Ranjha, Kora kagaz, Pyaasa Tere ghar ke saamne etc. if you are in tragic mood than you can listened to Baiju Bawra, Guide and the lists goes on and goes, it is best advised to look for a mixed song cassate, from a geniune music shop where you can get the songs of all moods, I had many of my own, even cds so if I am on internet also I am hearing Rafi Saab, it was a truly a legend and no body in thousand years can be like Rafi Saab
