Songfacts®:

• This anthemic tune is a collaboration between the Chainsmokers duo and the British band Coldplay. The dance floor-ready song was premiered with a live performance by both groups at the 2017 BRITS Awards on February 22, 2017.
• Coldplay's Chris Martin sings of a relationship that doesn't need to be superhumanly perfect:
  
  I'm not looking for somebody
  With some superhuman gifts
  Some superhero
  Some fairytale bliss
  Just something I can turn to
  Somebody I can kiss
  
  Though Chris Martin wants to be like mythological greats like Achilles and Hercules and comic superheroes such as Spiderman and Batman, he is well aware he's nothing like them. Fortunately his girl just wants a simple relationship with a straightforward guy.
  
  Chainsmokers explained: "This is about a relationship that doesn't need to be superhumanly perfect, an ordinary love, a love everyone deserves like the boy on the cover art whose childhood memories are now boxed up."
• The song was written by the Chainsmokers and Coldplay band members. It was produced by Chainsmokers with frequent collaborator DJ Swivel. The Canadian producer garnered a Grammy award for his work on Beyonce's song "Love On Top," which won in 2013 for best traditional R&B performance.
• The song's lyric video set a new mark on YouTube for single-day views. The clip was streamed more than 9 million times in its first 24 hours of availability, overtaking the previous record held by Justin Bieber's "What Do You Mean?" lyric video, which was played 8.2 million times in its first day.
  
  The record was smashed eight months later by the lyric video for Taylor Swift's "Look What You Made Me Do," which garnered more than 19 million views in its first 24 hours.
• The Chainsmokers are big fans of Chris Martin. Andrew Taggart told NME: "As a songwriter, he nails that hopeful, melancholy feeling that I grew up on."
• Most of the song was created during the Chainsmokers' first meeting with Chris Martin. They recalled:
  
  "We found some chords that everyone loved and then Chris plugged a mic into the PA in the studio and freestyled for an hour. This song was the result.
  
  We've never seen a song written in such a stream of conscious. It's hard to maintain your identity when working with such an established artist but we feel this song is great balance between both us and Coldplay."
• A live version of the song, recorded in Tokyo in April 2017, was included on Coldplay's Kaleidoscope EP.
