This defiant song is a strident kiss-off to those people who don't respect individuality. Merton explained:
"Being an artist and a human in this world always means confronting people who make you feel like you have to act according to their rules. Like most people, I wanted and still want to live by my own rules. The idea, or, if you like, the need, to write and record 'Lash Out' was born of a feeling within me."
"Lean On" was originally sent by Major Lazer to both Rihanna and Nicki Minaj's camps as a slower reggae track. After both parties rejected the tune, Major Lazer recruited Danish singer MØ to supply vocals and recorded it themselves.
