"Wasted Youth" follows on from "Red Bull & Hennessy", and "Heads Will Roll" featuring Ringo Starr.
The new single sees Benmont Tench (Tom Petty’s Heartbreakers) playing Vox Continental and Mellotron organs, and Don Was playing bass.
On The Line is Lewis' first album since 2014's The Voyager. Although Lewis hasn't released a new solo album in five years, she did drop her debut record in 2016 with her side project Nice As Fuck, which she performs in alongside Erika Forster and Tennessee Thomas.
Lewis revealed in a recent interview that she also contributed to Vampire Weekend's "2021" single.
