“Complicated” is the debut single by Avril Lavigne that skyrocketed the 17 year old vocalists to stardom, sporting record sales, and topping charts across the globe.
This singe not only made it into the BillBoard Hot 100, it was climbing fast and peaked at number two, making way for her first debut album release titled “Let Go” to strike hard across the western world.
It sold 3 million copies sold worldwide.
Not bad for some 17 year old kid that nobody had ever heard of.
