Sony Music Publishing today announced the signing of breakthrough singer-songwriter Sienna Spiro to a global publishing agreement.
With a timeless sound, captivating vocals and a gift for cinematic storytelling, Sienna has already made a remarkable impact across the music scene. At just twenty years old, she has amassed over 6.6 million monthly Spotify listeners and 1.5 million TikTok followers, while also earning co-signs from the likes of SZA, Snoh Aalegra, Finneas and Mark Ronson.
Sienna first propelled into the spotlight last year with her debut single “NEED ME,” and her momentum has only continued to grow since then. Her debut EP, SINK NOW, SWIM LATER, released in February 2025, has surpassed 122 million Spotify streams, while her viral hit “MAYBE.” has topped four global Spotify viral charts and generated over 600 million TikTok views. Recently, Sienna achieved her first-ever UK Top 10 with her powerful hit song “Die on This Hill,” marking her third career entry on the list.
Sienna said, “So honoured and excited to start my journey with Sony Music Publishing! I’m so grateful to everyone on the team who’s supported me, and I can’t wait for what’s ahead.”
Sony Music Publishing Vice President, Creative A&R Scout Easley and Director, Creative A&R, Adam Ikner said, “It’s clear Sienna’s vocals are undeniably special, but her voice as a songwriter is its own quiet force. Her instinct for emotional storytelling makes listeners not just hear her but feel every moment with her. We’re so excited to be a part of Sienna’s team and for everything that’s in store.”
Following her sold-out UK/EU headline tour, Sienna joined Sam Smith in support of their To Be Free: New York City residency. She has also taken the stage at festivals including All Points East and BBC Radio 1’s Big Weekend, in addition to supporting Teddy Swims on tour across the US.
