Surprised to see this massive hit being only the 5th most listened to song of the year? Since it was released in the beginning of February it has been overplayed on the radio and it has sold millions all over the world. The song's impact has been so incredible that it has reached number one in many countries including Italy, Spain, Canada and, of course, the United States. Sia's career has been going from strength to strength since she got her big break thanks to David Guetta's song Titanium, which was released in 2011, and it looks like her success isn't about to fade anytime soon!
