13. Rekha Bhardwaj
In an industry ruled by the likes of conventionally girly-voiced Alka Yagnik and Shreya Ghoshal, Rekha made her own mark. Her slightly nasal tone teases you into an unusual rustic seduction that you cannot fight. The maturity in her voice adds to the charm. There’s a distinct identity to all of her songs like ‘Judai’ (Badlapur), ‘Phir Le Aaya Dil’ (Barfi), ‘Kabira’ (Yeh Jawaani Hai Deewani) and ‘Darling’ (7 Khoon Maaf).
