For someone whose voice was deemed unfit for playback in his initial years, Singh has come a long way singing for almost all leading actors and working with top music directors. His association with AR Rahman has produced some of his career's most popular tracks. Their collaboration 'Jai Ho' from the film Slumdog Millionaire went on to win the Oscar for the Best Original Song. Singh had a very successful 2012 with more than 10 hits to his credit, most notably 'Tore Bina' from Kahaani.
