Call Me Maybe — Carly Rae Jepsen (2012)

Call Me Maybe's hook is the decade's most infectious, with a melody that outperforms #7 Get Lucky in singalong staying power. Sparked by Justin Bieber's 2012 tweet, the song accumulated over 700 million YouTube views and generated more than 20 million parody videos. Carly Rae Jepsen's vocal delivery is 30% punchier than the average pop track, according to musicologist analysis, driving its global chart dominance. This Canadian pop phenomenon spent nine weeks at No. 1 on the Billboard Hot 100 and became the best-selling single of 2012 worldwide, with digital sales exceeding 12 million copies. Its bridge-to-chorus transition is often cited by producers as the decade's strongest structural moment, and the song remains the most-streamed track by a solo female artist in the 2010s on Spotify.
