"Cold Water" is a song recorded by electronic music group Major Lazer, taken as the lead single from their fourth studio album, Music Is the Weapon (2017), featuring vocals from Canadian artist Justin Bieber and Danish singer MØ. It was written by Major Lazer member Diplo, Ed Sheeran, Nick Kibler, MØ, Justin Bieber, Jamie Scott, Benny Blanco, Philip "Jr. Blender" Meckseper and Henry "King Henry" Allen; the latter three also co-produced it with Major Lazer. "Cold Water" was released on July 22, 2016.

"Cold Water" was a weird one because I didn’t even know that song existed. It was a song I must’ve half-written somewhere at a time where I was writing a lot of songs and I did it at Benny Blanco’s house and then I got an email from Diplo just being like, "Yo! That 'Cold Water' song is dope! Can I have it?" And I was like, "I have no idea what you’re talking about," so I just didn’t reply. And then he emailed and was like, "Yo, Justin [Bieber] wants to hop on the 'Cold Water' song. Is that cool?" And I’m just like, "What are you talking about?"... And then the song came out and it was number one and I was like "Oh, that song!" I remember doing it, but it was really, really slow. I remember hearing it and being like "That kind of sounds like me. Oh wait, it was me."

The day before Diplo arrived in New York City in May 2016, he was "more than a little surprised" when Justin Bieber sent a message on Twitter about the track, "Cold Water", asking when it would be coming out. "That was not planned at all," Diplo said. According to Diplo, the song wasn't really done, when Bieber already expressed his excitement. "It's actually very real. Twitter is the only reason I know he's excited about the song. I don't have his number, so he Twitters at me", Diplo added. On May 30, Diplo announced Major Lazer's collaboration with Bieber and MØ. At the time, he did not give a specific release date, only mentioning it would be released "in a couple of weeks" and that it would premiere on Beats 1.

You can tell if something’s authentic or not… I felt like [MØ] was so ambiguous, having grown up singing pop and punk… Her word choice and her metaphors are just so foreign from American songwriters who tend to overuse the same phrases.
