Hey! Hey! Hey! Music Champ is a Japanese music variety show on Fuji Television hosted by the comedy duo Downtown, which consists of Hitoshi Matsumoto and Masatoshi Hamada. It is a very popular show with comical hosts who like to pick on their guests. An episode usually consists of live performances (of recently released songs) from popular artists, chat segments and other fun and games.

Many famous singers such as Ayumi Hamasaki, Britney Spears, Utada Hikaru, and Namie Amuro have performed almost all of their singles on this show. Japanese rock artists such as Glay, X Japan, Alice Nine, The Gazette, Nightmare, Gackt, and L'Arc-en-Ciel have also been on the show performing their hit singles as well as playing games with the hosts. All bands signed under Johnny & Associates have also appeared on the show as guests and have performed their latest hit songs. South Korean boybands Big Bang, TVXQ and girl groups Girls' Generation and Kara (band) have also appeared on the show.

In this quiz game segment, four or five teams of one or more individuals try to guess songs as they are played four at a time. (As each song is correctly guessed, they are eliminated from the mixture.) Each song has a descending point value, from 40 for the first song guessed to 10 for the last.

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.
