What Was Shawn Mendes’s First Song Ever Released?

The Story Behind “Life of the Party”: Shawn Mendes’ Historic First Song

Long before he was selling out massive arenas worldwide and headlining festival stages, Shawn Mendes was just a teenager in Ontario, Canada, strumming a guitar in his bedroom and posting six-second cover clips on the viral app Vine.

That digital hustle changed everything, transforming him from a social media content creator into one of pop music’s defining modern stars. At the heart of that transition was his official debut single: “Life of the Party.”

From Vine Clips to Island Records

In 2013, Mendes began uploading videos of himself singing snippets of popular songs—ranging from Justin Bieber to Lana Del Rey—gathering millions of views and a fiercely loyal fanbase. His acoustic style, soulful rasp, and genuine charm caught the attention of artist manager Andrew Gertler, who brought him to New York City.

By May 2014, at just 15 years old, Mendes signed with Island Records. Just weeks later, he released his very first professional single, “Life of the Party,” on June 26, 2014.

Breaking Records Right Out of the Gate

“Life of the Party” was an acoustic-pop ballad co-written by Ido Zmishlany and Scott Harris. It carried a message of teenage insecurity, self-acceptance, and finding the courage to be yourself even when you feel like you don’t fit in—themes that deeply resonated with his online community.

The track made an immediate splash on the charts, defying expectations for a newcomer who hadn’t yet been heavily pushed by traditional radio:

• It debuted at No. 24 on the US Billboard Hot 100.
• This achievement made the 15-year-old Mendes the youngest artist ever to debut in the top 25 of the Hot 100 with a debut single.
• It also served as the lead track for The Shawn Mendes EP before later being featured on his full-length debut studio album, Handwritten (2015).

Why It Still Matters Today

Looking back, “Life of the Party” captured a unique lightning-in-a-bottle moment in pop culture history. It bridged the gap between the old guard of the music industry and the new wave of internet-bred artists who built their careers from the ground up using social media.

While Mendes would go on to release massive global anthems like “Stitches,” “Treat You Better,” and “There’s Nothing Holdin’ Me Back”, “Life of the Party” remains the foundational cornerstone of his journey—the song that proved a teenager with a guitar and an internet connection could change the pop landscape forever.
