What Is Shawn Mendes’s First Song? The Story Behind His Debut

Long before he was selling out stadiums globally and headlining international charts, Shawn Mendes was just a 15-year-old teenager from Pickering, Ontario, recording six-second song covers in his bedroom. His official entrance into the music industry—his very first single—changed pop history forever.

The Track That Started It All: “Life of the Party”

Shawn Mendes’ first-ever single is “Life of the Party,” released on June 26, 2014, through Island Records.

Written by Ido Zmishlany and Scott Harris, the track is an acoustic-driven piano ballad rather than an upbeat party anthem. Its lyrics carry an empowering message about teenage self-identity, anxiety, and finding comfort in your own skin:

“We don’t have to be ordinary / Make your best mistakes / ‘Cause we’ve all got money to make / We’re the baddest ghouls and boys / It’s alive, it’s alive, it’s alive…”

Mendes immediately connected with the song’s core message, noting in interviews that it perfectly captured the awkwardness and pressure of growing up and trying to figure out who you want to be.

A Record-Breaking Debut

The release of “Life of the Party” wasn’t just a milestone for Mendes—it was a historic chart moment.

Supported by a massive, fiercely loyal fanbase he had built on the short-form video app Vine, the song went straight to number one on the iTunes charts within hours of its release. Shortly after, it debuted at number 24 on the US Billboard Hot 100.

This achievement made the 15-year-old Mendes the youngest artist in history to debut in the Top 25 of the Billboard Hot 100 with a first-ever single.

From Internet Star to Global Pop Icon

“Life of the Party” was first introduced on The Shawn Mendes EP in July 2014 before later being featured as a cornerstone track on his official full-length debut studio album, Handwritten (2015).

While subsequent mega-hits like “Stitches,” “Treat You Better,” and “In My Blood” would cement his status as a global superstar, “Life of the Party” remains the nostalgic time capsule of where the journey began—proving that a teenager with an acoustic guitar and an internet connection could shift the landscape of modern pop music.
