"Complicated" is a song by Avril Lavigne and was her debut single, released in 2002 from her debut album, Let Go. It was written by Lavigne and The Matrix (Scott Spock, Lauren Christy, and Graham Edwards), and produced by The Matrix. The single reached number one in Australia (for six weeks), New Zealand and Mexico (for nine weeks), number two on the Billboard Hot 100 and number three in the United Kingdom. Based on its chart performance, the song is Lavigne's second most successful single (only behind her 2007 single "Girlfriend") and was one of the most successful releases 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. "Complicated" was nominated for two Grammy Awards for Song of the Year and Best Female Pop Vocal Performance.

"Complicated" is a song about how people can be fake. Lavigne said about the song: "People sometimes bother me how they're not real and how they're just, like, putting on a face and being two-faced". Lavigne stated that she experienced this with both boyfriends and female friends.

Avril Ramona Lavigne (pronunciation: /ˈævrɨl ləˈviːn/; AV-ril lə-VEEN; born 27 September 1984) is a Canadian singer-songwriter. She was born in Belleville, Ontario, but spent most of her youth in the small town of Napanee. By the age of 15, she had appeared on stage with Shania Twain; by 16, she had signed a two-album recording contract with Arista Records worth more than $2 million. In 2002, when she was 17 years old, Lavigne broke onto the music scene with her debut album Let Go.

Let Go made Lavigne the youngest female soloist to reach No. 1 in the UK, and the album was certified four-times platinum by the Recording Industry Association of America. By 2009, over 16 million copies had been sold worldwide. Her breakthrough single, "Complicated", peaked at No. 1 in many countries around the world, as did the album Let Go. Her second album, Under My Skin, was released in 2004 and was her first album to peak at No. 1 on the U.S. Billboard 200, eventually selling more than 10 million copies worldwide. The Best Damn Thing, Lavigne’s third album, was released in 2007, becoming her third No. 1 album in the UK Albums Chart and featuring her first U.S. Billboard Hot 100 No. 1 single, "Girlfriend". Lavigne has scored six number-one singles worldwide, including "Complicated", "Sk8er Boi", "I'm with You", "My Happy Ending", "Nobody's Home", and "Girlfriend". With more than 30 million copies of her albums sold worldwide, Lavigne is one of the top-selling artists releasing albums in the U.S., with over 10.25 million copies certified by the RIAA. Her fourth studio album, Goodbye Lullaby, was released in March 2011. Goodbye Lullaby gave Lavigne her fourth top 10 album on the U.S. Billboard 200 and the UK Albums Chart and her third No. 1 album in both Japan and Australia. Three months after the release of Goodbye Lullaby, Lavigne began work on her fifth album, which will be released on Epic Records following her departure from RCA Records.

Alfred Matthew "Weird Al" Yankovic (pronunciation: /ˈjæŋkəvɪk/; born October 23, 1959) is an American singer-songwriter, music producer, accordionist, actor, comedian, writer, satirist, and parodist. Yankovic is known for his humorous songs that make light of popular culture and that often parody specific songs by contemporary musical acts. Since his first-aired comedy song in 1976, he has sold more than 12 million albums (as of 2007), recorded more than 150 parody and original songs, and has performed more than 1,000 live shows. His works have earned him three Grammy Awards among nine nominations, four gold records, and six platinum records in the United States. Yankovic's first top ten Billboard album (Straight Outta Lynwood) and single ("White & Nerdy") were both released in 2006, nearly three decades into his career.

Yankovic's success comes in part from his effective use of music video to further parody popular culture, the song's original artist, and the original music videos themselves, scene-for-scene in some cases. He directed later videos himself and went on to direct for other artists including Ben Folds, Hanson, Black Crowes, and The Presidents of the United States of America. In addition to recording his albums, Yankovic wrote and starred in the film, UHF, and television show, The Weird Al Show. He has also made guest appearances on many television shows, in addition to starring in Al TV specials on MTV.

Raised in Wyomissing, Pennsylvania, Swift moved to Nashville, Tennessee at the age of fourteen to pursue a career in country music. She signed to the independent label Big Machine Records and became the youngest songwriter ever hired by the Sony/ATV Music publishing house.

Swift's second album, Fearless, was released in late 2008. Buoyed by the chart success of the singles "Love Story" and "You Belong with Me", Fearless attracted a crossover audience and became the top-selling album of 2009. The record won four Grammy Awards, with Swift becoming the youngest ever Album of the Year winner. Fearless also received Album of the Year plaudits at the American Music Awards, Academy of Country Music Awards and Country Music Association Awards, making it the most awarded album in country music history. In 2010, Swift released her third album, Speak Now, which sold over one million copies in its first week. She then embarked on the 111-date Speak Now World Tour, which was attended by over 1.6 million fans and has become one of the highest-grossing concert tours of all time. The album's third single, "Mean", won two Grammy Awards for Best Country Song and Best Country Solo Performance.
