"No New Friends" is a pop song with electronic dance music (EDM) influences,[4] and has a "thumping" dance beat with "bouncy" synth loops by Diplo, as well as harmonized vocals by Sia and Labrinth. Jon Blistein of Rolling Stone describes the song's bridge as "reminiscent of a boozy piano ballad".[3]
Sia confirmed the song's release date via Twitter on 12 March 2019.[5] The group performed "No New Friends" on The Ellen DeGeneres Show in April 2019.[6]
Billboard's Kat Bein described "No New Friends" as a "bright, rhythm-led tune that pops warm and sunny like spring for your ears", and "infectiously catchy with a touch of the islands that celebrates the buddies we already have".[7] Derrick Rossignol of Uproxx called the song "upbeat" and "an ode to appreciating what you have". He wrote, "The song gives everybody a chance to shine, thanks to Sia's idiosyncratic vocals, Labrinth's hip-hop energy, and Diplo’s EDM-influenced pop production that ties everything together."[4]
The official music video for the song was released on 16 April 2019. Rolling Stone's review called the video "an appropriately fantastical visual" and described it as follows: "The clip, directed by Dano Cerny and choreographed by Ryan Heffington, stars Sia's sixteen-year-old body double Maddie Ziegler as a giant. She encounters the pink-clad Labrinth in a Dr. Seussian land of puff-ball trees and whimsical puffy clouds, and the two quickly form a bond. They frolic through the trees, stare up at cloud formations and encounter human-sized clones of Ziegler dancing giddily on a hillside. Diplo appears later in the video as a floating sun and moon, and as another giant who towers over Ziegler."[8]
