The Chainsmokers

You would think blending dance, pop, hip-hop and indie would be a complete mess but that's roughly an approximation of what American duo The Chainsmokers do – and they largely pull it off. Many people clearly agree with this sentiment considering the fact that since their breakthrough in 2014, they've been nominated for numerous awards and are certified platinum. Back in Hong Kong for their World War Joy tour, the pair will most likely perform their annoying earworms like Roses and Something Just Like This.
