Background and release
On 9 September 2026, Rosé and Apple announced the song "New Trick" would be released on 17 September as part of the company's "Shot on iPhone" campaign, to coincide with the release of the iPhone 18 Pro. The announcement was accompanied by a 15-second teaser on Instagram, which featured a brief snippet of the track and showed Rosé holding a purple lollipop with the words "new trick" on the wrapper.
Following the song's release, Rosé appeared on Apple Music's radio show New Music Daily Radio with Zane Lowe to discuss the collaboration.
Composition and lyrics
"New Trick" has been described as a garage punk, pop punk, synth-punk, and pop rock track. It has been also been characterised as a dreamy, uptempo alt-pop anthem that channels the "iconic energy of 90s romcoms" and the "punk rock edge of the early aughts". Stylistically likened to Olivia Rodrigo, the song incorporates a "grungy, high-energy production" accompanied by a scream-along chorus and vocally "syrupy sweet" verses.
The song was written in May 2026 "during a hectic week", two days after Rosé attended the Met Gala. Written by the singer with frequent collaborator Amy Allen and producer Andrew Wells, "New Trick" marked a departure from the sadder songs Rosé had written for her debut studio album Rosie. Lyrically, it addresses heartbreak with an attitude towards recovery rather than loss, and showcases Rosé charmingly replacing vulnerability with "humour, self-possession, and forward momentum". Rosé has further described the track as the "cutest thing we’ve ever made together", saying she enjoyed "channeling that energy" while recording it.
