The song was written and composed by Wayne Hector, Ed Drewett, Matt Rad, along with the band's regular collaborators Julian Bunetta and John Ryan.

For example, Will Hermes from Rolling Stone gave "Best Song Ever" a score of 4 out of 5 stars, describing the track as "pretty irresistible".

[2] Lewis Corner at Digital Spy also awarded the song 4 out of 5 stars, writing: "Sure the lyrics are cheesier than a 6-pack of Wotsits, and yes the sentiment is cornier than a Disney Channel rom-com, but as far as boyband pop anthems go it skirts dangerously close to fulfilling its title.

[4] The music video for "Best Song Ever" was directed by Ben Winston and written by comedian James Corden.

[5] Filmed over two days at The Temple House in Miami Beach, Florida,[6] the video was released on the band's Vevo channel on 22 July 2013.

The studio executives are stoked to take the band to the proverbial next level, but they proceed to bring in an under-qualified crew consisting of Marcel, "The Marketing Guy" (Harry Styles) and Leeroy, "The Choreographer" (Liam Payne).

Interspersed with scenes from their film One Direction: This is Us, the band are shown wreaking havoc throughout the office and even throwing in a few dance moves for good measure.
