The list kicks off with the fourth single from Lavigne's multi-platinum debut, 'Let Go.' The 2003 hit features scorned lyrics, which are paired with dark guitars that help showcase the singer's rock edge. Although it had big shoes to fill, the last release from the ever-so-successful album was distinguished by a 2004 Grammy nomination for Best Female Rock Vocal Performance.
'Don't Tell Me'
Despite its seemingly vulnerable intro, the debut single from the Canadian star's sophomore album, 'Under My Skin,' is just as tough as any of her hits. The empowered song gives the proverbial hand to a guy who thinks Lavigne is easy, and delivers the message with classic pop grandeur. It also earned the singer a nomination for Best Pop Video at the 2004 MTV Video Music Awards.
'When You're Gone'
Lavigne's big pop ballad tugs at heartstrings and expresses the sentiments of anyone who's ever had to say goodbye to a loved one. The song was written by the singer and her longtime collaborator Butch Walker, and has an accompanying video that features three forlorn situations. The imagery scored People's Choice: Favourite Canadian Artist award at the 2008 MuchMusic Video Awards.
The third single from 'Under My Skin' was co-written by Lavigne and Evanescence guitarist Ben Moody. The rock ballad touched fans in 2004 with its simple lyrics, depicting a lost girl: "She wants to go home / But nobody's home / That's where she lies / Broken inside." It peaked at No. 13 on Billboard's Mainstream Top 40 chart.
Lavigne charmed millions by crashing the mall in the video for her debut single from 'Let Go.' In 2002, the smash hit held the No. 1 position at radio for eleven weeks in a row, and was nominated for two Grammy Awards for Song of the Year and Best Female Pop Vocal Performance. The song also reached No. 1 on Billboard's Mainstream Top 40 and No. 2 on the Hot 100.
'Keep Holding On'
While 'Keep Holding On' appears on Lavigne's third album, 'The Best Damn Thing,' the song was initially released as the theme song for the 2006 film 'Eragon.' The power ballad, co-written by the pop star and super producer Dr. Luke, earned the singer a 2007 Academy Award nomination for Best Original Song. It later won Best Pop Song at the 2008 Socan Awards.
In the second single from her debut album, 'Let Go,' Lavigne sings of an age-old lesson: "Don't judge a book by its cover." The song, which was produced by the Matrix, helped to establish the then-18-year-old as an international pop star, reaching No. 1 in six countries. It also earned Lavigne a Juno Award, a Teen Choice Award and a Socan award, as well as a nomination for Best Female Rock Vocal Performance at the 2003 Grammys.
'My Happy Ending'
Breaking up is hard to do for Lavigne in her defining 'Under My Skin' track. The undeniably catchy song (who could forget that pre-chorus?) reached No. 1 on the Billboard Mainstream Top 40 chart, and was heavily licensed for film and TV, landing placements in 'CSI: Crime Scene Investigation,' 'Smallville,' 'Gilmore Girls' and 'Bring It On: All or Nothing.'
'Girlfriend' became Lavigne's first No. 1 single on the U.S. Billboard Hot 100, and with its unforgettable cheer-chant chorus, it's no mystery why. The lead single from 'The Best Damn Thing' also reigned at No. 1 in over 10 countries, and sold over 7 million copies worldwide. It was remixed several times -- most notably by Dr. Luke, featuring Lil Mama -- and its official video boasts over 139 million views on YouTube.
'I'm With You'
Following the release of 'Complicated' and 'Sk8er Boi,' the world came to understand Lavigne's musical depth with the third single from her debut album, a ballad. It earned the pop star her first two Grammy nominations for Best Female Pop Vocal Performance and Best Pop Song in 2004. It peaked at No. 1 on Billboard's Mainstream Top 40, and is also No. 1 on our Top Avril Lavigne Songs list.
