What Was Shawn Mendes’s First Song?

From Vine Star to Global Pop Icon: The Story Behind Shawn Mendes’ First Song, “Life of the Party”

Long before he was headlining stadium tours, filling radio waves with acoustic-driven anthems, and cementing his status as a global pop staple, Shawn Mendes was just a teenager in Toronto teaching himself guitar via YouTube tutorials.

In 2013, everything changed when he began posting six-second song covers on the short-form video app Vine. Armed with a soulful voice, an acoustic guitar, and an undeniable charm, Mendes quickly amassed millions of followers. But social media virality was only the beginning. In June 2014, a 15-year-old Mendes took the ultimate leap from internet sensation to bona fide recording artist by releasing his debut single, “Life of the Party.”

Anatomy of a Debut: What is “Life of the Party”?

Written by Ido Zmishlany and Scott Harris, “Life of the Party” was introduced as the lead single from The Shawn Mendes EP and later featured on his chart-topping 2015 debut studio album, Handwritten.

Initially, the songwriters had toyed with a faster, more upbeat tempo. However, sensing that the rhythm didn’t match the emotional core of the track, they stripped it back into a poignant, piano-driven acoustic ballad. The lyrics served as a comforting, empowering anthem for teenagers struggling with identity, self-doubt, and the awkward pressures of fitting in:

“We don’t have to be ordinary / Make your best mistakes / ‘Cause we don’t have the time to be sorry / So baby be the life of the party.”

For Mendes, the song’s message resonated deeply with his own journey of growing up in the public eye. It wasn’t just a catchy introduction to his music; it was an emotional lifeline sent out to fans experiencing the exact same adolescent insecurities.

A Record-Breaking Debut

The release of “Life of the Party” didn’t just introduce a new artist—it shattered records.

Driven by an intensely loyal fanbase cultivated on Vine, the track skyrocketed to number one on the iTunes charts within hours of its release. More impressively, it debuted at number 24 on the US Billboard Hot 100. This monumental feat made a 15-year-old Shawn Mendes the youngest artist in history to debut in the top 25 of the Hot 100 with a debut single.

Setting the Stage for Stardom

Looking back, “Life of the Party” acted as the perfect blueprint for Shawn Mendes’ career. While later hits like “Stitches” and “Treat You Better” leaned into punchier, radio-friendly pop-rock grooves, his debut single established the vulnerable, organic storytelling that his fans fell in love with.
