Let Go

Let Go was released on June 4, 2002 in the United States, it has reached number two there and number one in Australia, Canada, and the United Kingdom. This made Lavigne, at seventeen, the youngest female soloist to have a number-one album in the UK up until that time.

The album shows definite pop rock/indie pop roots; however, alternative and post-grunge influences can be heard in some of the songs.

Just over one month after its release, Let Go reached multi-platinum status in late-August, and was certified triple platinum two weeks after. Before the end of 2002, just six months after its debut, it was certified four times platinum by the RIAA. It sold a total of 14 million copies worldwide. It was the best selling album of the year for a female artist and for a debut album in 2002. As of December 2007 the album has sold 6.6 million copies in the U.S and more than 16 million worldwide.

Four singles from the album were released. The first single, "Complicated" went to number one in Australia, while reaching number two on the U.S. Hot 100, and it was one of the best-selling Canadian singles of 2002. Lavigne tied a record set by Natalie Imbruglia's "Torn" when Complicated held the number one spot on the contemporary hit radio chart (which tracks air play on the radio) for eleven weeks in a row. Sk8er Boi reached the top ten in the U.S. and Australia, "I'm with You" reached the top ten in the U.S and the UK, and "Losing Grip" reached the top ten in Taiwan and the top twenty in Chile.

Lavigne was named Best New Artist at the 2002 MTV Video Music Awards, won four Juno Awards in 2003 (out of six nominations), received a World Music Award for World's Best-Selling Canadian Singer, and was nominated for eight Grammy Awards, including "Song of the Year" for Complicated and "Best New Artist".
