Some context: The Undertones are a punk rock/new wave band formed in Derry, Northern Ireland, in 1974. From 1975 to 1983, the Undertones consisted of Feargal Sharkey (vocals), John O'Neill (rhythm guitar, vocals), Damian O'Neill (lead guitar, vocals), Michael Bradley (bass, vocals) and Billy Doherty (drums). Much of the earlier Undertones material drew influence from punk rock and new wave; the Undertones also incorporated elements of rock, glam rock and post-punk into material released after 1979, before citing soul and Motown as the influence for the material released upon their final album. The Undertones released thirteen singles and four studio albums between 1978 and 1983 before Sharkey announced his intention to leave the band in May 1983, citing musical differences as the reason for the break up.
The Undertones formed in Derry, Northern Ireland in 1974. The band members were five friends from Creggan and the Bogside, who originally drew inspiration from such artists as the Beatles, Small Faces and Lindisfarne. The band initially rehearsed cover versions at the home of the guitarists, brothers John and Vincent O'Neill, and in the shed of a neighbour. (In early 1976, before the band had played gigs at any venues, Vincent O'Neill left the band; being replaced by his younger brother Damian.) Beginning in February 1976 the group, at this stage still unnamed, began playing gigs at various minor local venues, including schools, parish halls and Scout huts, where the band's lead singer, Feargal Sharkey, was a local Scout leader. Sharkey was also responsible for giving the band their first name: at the introduction to a gig at Saint Joseph's Secondary School in Derry on 16 March 1976, Feargal Sharkey was asked the name of the band and quickly replied "The Hot Rods". At a later gig, Sharkey named the band "Little Feat": another name already used by another group. Later that year, drummer Billy Doherty proposed an alternate name for the group: The Undertones, which Doherty had discovered in a history book. The other members of the band agreed to the proposal. With the arrival of punk rock in late 1976, the artistic focus of the band changed. Artists such as the Adverts, Sex Pistols, the Buzzcocks and, particularly, the Ramones became major influences on the Undertones. In addition to being a scout leader, Feargal Sharkey worked as a television repairman and delivery man. The van which Sharkey drove in this employment was used by the Undertones to transport their equipment to and from various venues.

Some context: A-Teens (stylized as A*Teens) were a Swedish pop music group from Stockholm, Sweden, formed by Niklas Berg in 1998 as an ABBA tribute band called ABBA Teens and later renamed A-Teens. The band members were Marie Serneholt, Amit Sebastian Paul, Dhani Lennevald and Sara Lumholdt. The band's debut album became a success around the world and in 2001 it was reported that the band had sold 6 million albums worldwide. After six years together, the band announced they would take a break in 2004 after the release of their Greatest Hits album.
The band's second album, entitled "Teen Spirit", featured a compilation of tracks that were not ABBA covers and when it was finally released on 26 February 2001, it debuted at number two in the Swedish Charts.

Prior to the release of the album, the A-Teens became one of the first bands to broadcast one of their shows on MSN's Websites. The UK releases were delayed due to A-Teens' failure with their previous album in that country. When "Upside Down" was released there in May 2001, it became their biggest hit in the country. The single peaked at number ten in the United Kingdom becoming their only top ten hit in that country. The album was delayed and released after the second single, "Halfway Around The World" in late October 2001. The single barely made the top thirty and the album did not chart in the top 75. Before they started their concert tour in the U.S. the band went to promote their album to Asia, with stops in Japan, Singapore, Malaysia where they did show for MTV Asia and Thailand, with great success, especially in the former where Coca-Cola signed the band to become the face of the brand there and promote, "We were the first international artists ever to appear on a soda can there. They printed 15 million of them; we went home with ten!" Remembers Sara, The cans were distributed around the country that year.

The group promoted their album with a forty-three-date tour with Aaron Carter around the U.S. Back in Europe, the band toured with No Angels in Germany. By the end of 2001, Teen Spirit went on to sell over 1 million copies worldwide and were invited by Walt Disney/Buena Vista to record the European soundtrack for the movie "The Princess Diaries". As the movie had already been released in North and South America, the movie was set to be released in Europe in the winter 2001. "Heartbreak Lullaby" a song written by Cathy Dennis (famous for writing Kylie Minogue's number one hit, "Can't Get You Out of My Head") and Kasmanaut, the video was shot in Germany in late October, in the middle of their tour. The single was released in December 2001 and it became another top ten hit for the band in their home country spending four months inside the charts.
