Little May are an Australian folk-rock trio, comprising vocalist Hannah Field and guitarists Liz Drummond and Annie Hamilton. Drummond told Billboard magazine that she penned this song in an hour after the girls had been inspired by listening to Big Scary's "Thinking About You."
Field nailed the vocals on her first attempt. "Hannah's lyrics are exactly the same as when she first sang them," Drummond said. "She's good like that. We recorded it on a voice memo and over time, re-jigged the structure and built upon it during rehearsals."
"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.
