All We Know was released in 2016 by American DJ duo The Chainsmokers, featuring American singer Phoebe Ryan, following their breakthrough hit Closer. Built around piano, tropical house influences, and a downtempo electropop drop, the song became a staple of mid-2010s pop playlists. Online, short excerpts circulate on soundboards as instant mood cues, allowing editors to reference the whole track with a single recognisable fragment rather than using the full recording in videos, edits, and social posts.
