Nathaniel Rateliff & the Night Sweats close their eponymous debut studio album on a hopeful note with this relatively laid-back cut. "Originally, I had it ending with a song called 'How to Make Friends,' Rateliff said. "The chorus is 'When everybody knows you, nobody's gonna want you.' (Laughs). But I replaced it with 'Mellow Out,' which is more of a release rather than a total bummer."
