So far Andrew Taggart and Alex Pall, the duo that comprises the EDM group The Chainsmokers, are the masters of creating yearly hits. In 2014, it was the group’s song “#Selfie” that garnered them recognition. Last year, “Roses” was warbled on dance floors and blasted in cars everywhere. It was a song that bonded people with diverse musical inclinations all through summer ending, the leaves changing and our waiting for the snow that never came. Perhaps “Don’t Let Me Down” is The Chainsmokers’ triumphant 2016 single.
