The Canadian indie rocker co-wrote several tracks on the album, including "Substance," "Happy Ending" and "City of Angels." The source says that the pair have "a lot in common," including the fact that they are both on journeys of sobriety; Jutes marked 100 days sober in July, while Lovato has openly discussed her sobriety following a 2018 drug overdose.
