Nightingale's high notes

Lata Mangeshkar is undoubtedly the Nightingale of India. The singer, who turned 80 this year has sung over 25,000  songs! So there can be no agreement on her five best songs.
But a survey recently pointed out her top five  songs:
1. Pyar Kiya To Darna Kya? (Mughal-e-Azam, Music — Naushad)
2. Allah Tero Naam (Hum Dono, Music — Jaidev)
3. Piya Tose Naina Lage Re (Guide, Music — S D Burman)
4. Kahin Deep Jaley Kahin Dil (Bees Saal Baad, Music — Hemant Kumar)
5. Rahein Na Rahein Hum (Mamta, Music — Roshan)
