The Kid LAROI & Justin Bieber’s “Stay” (2021) was an unavoidable pop juggernaut. The high-energy breakup song, driven by a catchy synth hook and urgent vocals, spent seven weeks at #1 on the Billboard Hot 100 and became one of the most-streamed songs of the year. “Stay” also made the Kid LAROI the youngest artist in decades to top the chart. The song’s massive success (propelled by TikTok dances and constant radio play) cemented the Australian teen and the Canadian superstar’s collaboration as a defining hit of 2021.
