It reached number one in several other countries including Argentina, Australia, Denmark, Finland, Ireland, the Netherlands, New Zealand, Mexico, and Switzerland; as well as the top 10 in Austria, Belgium, Canada, Colombia, France, Israel, Italy, Norway, Poland, Spain, and Sweden.

[10] Regarding the creative process behind "Lean On", producer Diplo of Major Lazer said, "We wrote this song with MØ very early from an instrumental Jr Blender created in some sessions in Trinidad.

After he did his thing, me, MØ and Blender rewrote the song at the new tempo in Las Vegas and made something very unique that became our album's lead-off single.

[13] Consequence of Sound's Michelle Geslani called the song a "bouncy banger" and complimented MØ's "siren-like" vocals.

[14] David Jeffries from AllMusic praised MØ and DJ Snake for helping the track "deliver the sentimental lyrics and sensual house music at an intoxicating half-speed tempo.

"[15] Billboard's Matt Medved praised the song, explaining, "Lean On" gives Major Lazer’s reggae, trap and moombahton blend a pop gloss.

Despite being independently released, the infectious three-minute single became the poster child for dance crossover, dominating both radio and festival play and hitting No.

The accompanying music video for "Lean On" was directed by Tim Erem,[22] produced by Mikhail Mehra, Akshay Multani & Per Welen, director of photography Jacob Møller.

[23][24] It follows a premise of Major Lazer, MØ and DJ Snake engaging in modernised Bollywood dance sequences.

Major Lazer has always been a culture mashup and to us, India feels like some kind of special creature with one foot in history and one firmly in the future.

Zach Frydenlund of Complex wrote; "While the song was already catchy as hell, Ty Dolla adds another element to the single".

[31] Rap-Up also gave a positive review to the remix with writing that Ty Dolla Sign starts the song with "electrifying verse that is guaranteed to get you lit".

[32] Elias Leight of The Fader wrote that Ty Dolla Sign added "some extra juice" to the song with his verse.
