"Don't Let Me Down" is a song by American DJ duo The Chainsmokers. It was released the follow-up single to "Roses" on February 5, 2016, through Disruptor and Columbia Records. The song features vocals from American singer Daya.
Robbie Daw of Idolator stated "[Don't Let Me Down] kicks off with a haunting guitar loop and 17-year-old Daya lamenting that she's 'hit a wall, right now I need a miracle.' By the time the chorus sweeps in, the song shifts into full-on trap mode." and called it a "trappy collaboration". Popdust's Jason Scott claimed "[Don't Let Me Down] is an enormously engaging strip of gritty dance-club euphoria. Percussion vibrates underneath a well-constructed skyscraper of synth and evocative vocals from the 17-year-old Daya."
