If there was any debate that The Chainsmokers are two of the hardest working guys in the dance music industry, their 2019 Ultra Main Stage set closes that case. Alex and Drew not only closed down the festival on its main stage but did so in spectacular fashion.

While Ultra Music Festival is known for the massive amount of new music debuted over the weekend, The Chainsmokers took things a step further. Throughout their hour-plus set, the guys dropped THIRTEEN never before heard singles and edits. That's right – over 10 unreleased tunes graced this set throughout.

Thanks to 1001 Tracklists we have compiled the timestamps for each unreleased song. So you can browse through them at your leisure using the set embed below. It certainly feels like a new Chainsmoker's album is on the horizon in 2019.
