“All We Know” is a relaxed song about a struggling relationship. The relationship in question is on the brink of falling apart, but a connection still exists through some sort of love and/or weed, and the lovers don’t know whether to keep the relationship going or not.

The song features vocals from LA-based singer-songwriter Phoebe Ryan, and is the fourth original song released in 2016 by The Chainsmokers, following the success of their #1 hit, “Closer.”

After previewing the song at various live appearances in late August, The Chainsmokers confirmed the song would be their next single in early September 2016. Phoebe Ryan teased it on her Twitter four days before and the YouTube audio was released one day before the song’s official release on September 30th.
