American DJs Andrew Taggart and Alex Pall started in 2012 with their project The Chainsmokers. Their first hit was in 2014 with #Selfie (which of course we did not include in this top 10). But their first hit turned out to be a mistake and the music they released afterwards was much better. In recent years they score hit after hit and they haved worked together with the biggest names in the music industry.
