‘'13’‘ is the eighth track of LANY’s eponymous album, and the last single to be released in anticipation of the album. This song was a long time in the making: Klein came up with the song’s bouncy guitar riff when he was just 18. In its ten-year development, the song was shaped up to include Jake Goss’ signature beats.

On Twitter LANY stated:

it’s called “13” because we wrote and recorded it in one day – july 13, 2016. you can listen to it now if you want 🌹
