Singh took the industry by storm in 2013 with 'Lungi Dance'-a tribute to superstar Rajinikanth in Shah Rukh Khan's Chennai Express. The Punjabi rapper, who scores a million YouTube hits for his music videos, followed it up with 'Aaj Blue Hai Pani Pani' in the youth film Yaariyan. It became a rage and confirmed him as the go-to guy for 'item' songs. It is rumoured that Singh charges nearly a crore for every song he composes, making him the highest-paid musician in the history of Bollywood. His new release 'Blue Eyes' was launched digitally and picked up 10 million views on YouTube in 20 days.
