Background: KAT-TUN (katoun, Katun) is a Japanese boy band formed under Johnny & Associates (Johnny's) in 2001. The group's name was originally an acronym based on the first letter of each member's family name: Kazuya Kamenashi, Jin Akanishi, Junnosuke Taguchi, Koki Tanaka, Tatsuya Ueda, and Yuichi Nakamaru. Their debut on March 22, 2006 was marked by a tripartite release of a CD single, album and music DVD on their exclusive record label J-One Records. Since then, all of their single, album and music DVD releases have debuted at number one on the Oricon music and DVD charts.
Context: On March 22, KAT-TUN released their debut single "Real Face", accompanied by an album, Best of KAT-TUN and a DVD Real Face Film. These were released on their own label J-One Records. The group also went on a nationwide tour, Live of KAT-TUN "Real Face", in support of the album. Within the first week, Best of KAT-TUN, "Real Face" and Real Face Film topped all three Oricon weekly charts by selling 556,548 copies, 754,234 copies and 374,202 copies respectively. They became the second artists to do so, the first being Ayumi Hamasaki. With these numbers, KAT-TUN holds the record for the highest weekly single debut sales (previously held by Arashi with their debut single "Arashi" of 557,000 copies sold in 1999). In addition, "Real Face" topped the Oricon charts for three weeks straight, becoming the first debut single to do so in Japan in 8 years 8 months since KinKi Kids' debut single "Garasu no Shonen." The single sold over a million copies in nine weeks, making "Real Face" the highest selling single for the year 2006. In March 2006, KAT-TUN became the first group to hold their own performances in Japan's most popular stadium, Tokyo Dome, before debuting. They performed to 110,000 people over two days and about 630,000 people in total during the tour. About three months after releasing "Real Face", KAT-TUN released their second single, "Signal", on July 19. On October 12, member Akanishi announced a hiatus from the group in order to study linguistics abroad in the United States, leaving KAT-TUN as a five-member group for six months. The remaining members continued activities by releasing their third single, "Bokura no Machi de" as the theme song to members Kamenashi and Tanaka's drama, Tatta Hitotsu no Koi and their second album, Cartoon KAT-TUN II You on December 7. KAT-TUN is the first group in Japan to have all three singles from debut to exceed 500,000 in yearly sales, taking first, fifth and thirteenth place on the Oricon yearly singles chart.

Background: The Sugababes are a British girl group formed in 1998 by Siobhan Donaghy, Mutya Buena and Keisha Buchanan. Their debut album, One Touch, was released in the UK through London Records on 27 November 2000. The album achieved moderate success, peaking at number 26 in April 2001 and eventually being certified Gold. In 2001, Donaghy departed the group amid rumours of a rift with Buchanan and the group were dropped by their record label.
Context: Having already started work on a second album with new member Range, the trio looked for a new record label, eventually signing to Island Records. Their first single on the new label, "Freak like Me" scored the group their first UK number 1 single. Follow-up single "Round Round" also debuted on top of the UK Singles Chart and peaked at number 2 in Ireland, the Netherlands and New Zealand. Both singles were certified silver by the BPI. On the back of the success of the singles, the group's second album, Angels with Dirty Faces, debuted at number 2 on the UK Albums Chart and was later certified triple platinum, selling almost a million copies in the UK alone. It is to date their highest-selling album. In the UK, the third single from the album, a ballad titled "Stronger", gained the girls their third consecutive top ten hit in their native country. The track was released as a double-A side with "Angels with Dirty Faces" in the UK, the latter song chosen as the theme tune to The Powerpuff Girls Movie. A fourth single, the Sting-sampling "Shape", made the top ten in the Netherlands and Ireland in early 2003. The group's third album, Three, was released in late 2003 and reached number 3 on the UK Albums Chart, earning the group a BRIT Award nomination for Best Album. Certified double platinum, it has sold 855,000 copies to date. The album was preceded by lead single "Hole in the Head", which became the group's third UK number 1 single. It also reached number 2 in Ireland, the Netherlands and Norway, and became the Sugababes' first (and to date only) single to chart in the United States, reaching number 96 on the Billboard Hot 100. Follow-up single "Too Lost in You" appeared on the soundtrack to the film Love Actually and went top ten in Germany, the Netherlands, Norway and the UK. The album's third single, "In the Middle", was released in 2004 and garnered the group another BRIT Award nomination for Best Single; like its successor, the ballad "Caught in a Moment", it went to number 8 on the UK Singles Chart. In 2004, the trio sang on the Band Aid 20 remake of "Do They Know It's Christmas?", which went to number 1 in the UK in December. Around this time, the group's perceived "moodiness", alleged backstage catfights, and press junket tantrums were tabloid fodder in Britain. They were surrounded by continuous rumours of in-fighting within the group and constant split reports. Rumours suggested that Buchanan and Buena had bullied Range, although Range herself repeatedly denied such allegations; Buena later admitted that she "just didn't talk to her" when she first joined. Buchanan claimed there was only one serious fallout between herself and Range during a 2004 gig in Dublin, regarding Britney Spears' "Toxic".
