What Was Shawn Mendes’s First Song? The Story Behind It

The Track That Started It All: The Story Behind Shawn Mendes’ First Song, “Life of the Party”

Long before he was filling massive stadiums, headlining global tours, and cementing his status as a pop icon, Shawn Mendes was just a teenager in Ontario, Canada, uploading six-second covers to the short-form video app Vine.

When the transition from internet phenomenon to bonafide pop star officially happened, it rested squarely on the shoulders of one track: “Life of the Party.”

Released on June 26, 2014, as his debut single (and later serving as the lead track on The Shawn Mendes EP and his full-length debut studio album, Handwritten), “Life of the Party” did much more than introduce a new voice to the radio—it broke records and changed music industry history.

A Record-Breaking Debut

Written by Ido Zmishlany and Scott Harris, “Life of the Party” is an acoustic-driven pop ballad carrying an empowering message about staying true to yourself, dealing with anxiety, and not feeling pressured to fit into social molds (featuring memorable lines like, “We don’t have to be ordinary / Make your best mistakes / ‘Cause we don’t have to change”).

At the time of its release, Shawn Mendes was only 15 years old. The song immediately struck a massive chord with his rapidly growing online fanbase. Within hours of dropping, it skyrocketed to the top of the iTunes charts.

When the official Billboard charts rolled in, “Life of the Party” debuted at No. 24 on the US Billboard Hot 100. This milestone instantly etched Mendes into the history books: he became the youngest artist ever to debut in the top 25 of the Hot 100 with a debut single.

From Vine to Global Stardom

The success of “Life of the Party” proved to the music industry that digital creators and internet-bred talent possessed serious commercial viability. It bridged the gap between Mendes’ viral social media presence and traditional mainstream credibility. Island Records took notice early, signing him and positioning him not as a fleeting internet fad, but as a legitimate singer-songwriter capable of playing guitar and writing emotionally resonant hooks.

Looking back, “Life of the Party” laid the foundational blueprint for Mendes’ entire career: honest lyricism, organic instrumentation, and a deeply passionate connection with his listeners. Though his sound has evolved over the years through massive hits like “Stitches,” “Treat You Better,” and “In My Blood”, that very first single remains the official starting point of a remarkable musical journey.
