Complicated

Avril Lavigne’s “Complicated” (2002) was the pop-punk anthem that launched the teen rocker’s career. With a catchy acoustic guitar riff and lyrics about people putting up fronts, it struck a chord with young listeners. The song raced up the charts (hitting No. 2 on the Billboard Hot 100) and turned Lavigne into an instant global star, making “Complicated” a defining teen anthem of the early 2000s.
