Some context: Griffey was born in Donora, Pennsylvania, on November 21, 1969. (He shares a birthday with another Donora native and Hall-of-Famer, Stan Musial.) His family moved to Cincinnati, Ohio, where his father, Ken Griffey Sr., played for the Cincinnati Reds, when Ken Jr. was six years old. Ken Jr. was in the clubhouse during his father's back-to-back championships in the 1975 and 1976 World Series.
As a free agent, Griffey was courted by the Mariners and the Atlanta Braves. The national media was dubious about Griffey's declining skills, with The Washington Post noting "...the Mariners are not about to sign Griffey for baseball reasons; they're bringing him back to Seattle to sell tickets." Griffey ultimately accepted a contract offer from the Mariners on February 18, 2009, after "agonizing" over the decision. Griffey indicated he was motivated by sentimental reasons toward Seattle, where he received an overwhelmingly positive reception when he last played there as a Cincinnati Red in June 2007, but was inclined towards the Braves for its proximity to his home in Orlando, Florida, and his desire to be with his family during the season. Apparently, Griffey was very close to signing with the Braves; however, a premature report emerged from The Atlanta Journal-Constitution that an Atlanta deal was done and a conversation with Willie Mays and his own 13-year-old daughter played a factor in his choice. Griffey once again sported #24 with the Mariners; the team had not issued the number to any player or coach in the nine years between his two stints in Seattle.  Griffey went 1-2 with a home run in his regular season debut against the Minnesota Twins. The home run was Griffey's eighth Opening Day home run; as of 2013, he is tied with Frank Robinson and Adam Dunn for first place in this category. On April 15, 2009, Griffey hit his 400th home run as a Mariner (613th of career), off Los Angeles Angels pitcher Jered Weaver, becoming the first MLB player to hit 400 home runs with one club (Mariners) and 200 home runs with another (Reds). AP stated, "Griffey returned to the Mariners in 2009 and almost single-handedly transformed what had been a fractured, bickering clubhouse with his leadership, energy and constant pranks."  On June 23, 2009, at Safeco Field, Griffey hit the 5,000th home run in franchise history, off San Diego Padres pitcher Chad Gaudin. This was Griffey's 619th career home run. On September 1, Griffey hit career home run #621 at the new Yankee Stadium, off Yankees pitcher Andy Pettitte in the sixth inning. It marked the 44th different ballpark in which he had hit a home run. On August 12, 2009, against his former team, the Chicago White Sox, he hit an RBI single in the bottom of the 14th inning to win the game, 1-0, for the Mariners.  Griffey returned to the Mariners for the 2010 campaign with a similar contract to that of 2009, but struggled offensively over the first two months while posting a .184 batting average. On April 27, Griffey passed Andre Dawson for 45th on the career hit list. On May 20, 2010, in a game against the Toronto Blue Jays, Griffey hit an RBI single off Blue Jays' closer Kevin Gregg to win the game, 4-3, for the Mariners. After starting the ninth inning trailing 3-1, the Mariners rallied in the bottom of the ninth to load the bases on two singles and a walk, then tied the game via a walk and a sacrifice fly. The walk-off single was the final hit and RBI of Griffey's Major League Baseball career, and moved him past Rafael Palmeiro to 14th on the all-time RBI list.

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.
In 1998, Marie, Sara, Dhani, and Amit were musically united as the ABBA Teens. However, the group's name was changed to the A-Teens to avoid litigation. This choice allowed the band more freedom in creating their own style of music.  In early 1999, the band started the recording process of what would be their debut album, The ABBA Generation, consisting purely of ABBA covers reinterpreted with a modern pop and electronic flair to appeal to a new generation of young pop fans. Their first single, "Mamma Mia", topped the charts in over ten countries including their home country Sweden where it stayed at number one for eight consecutive weeks. The album hit the peak position in Sweden & Chile and became a top ten hit throughout the world. Further singles enjoyed similar success ensuring top ten placings across the globe, and the album overall sold more than 3 million copies worldwide, being certified Gold or Platinum in over 22 different countries.  The band's music video for "Dancing Queen" features a plot very similar to the 1985 John Hughes film The Breakfast Club. In addition, the principal seen in the music video was played by Paul Gleason, the same actor who was the principal in the film. The single reached ninety-five on the Billboard Hot 100 and sold over 500,000 copies in the U.S. alone, being certified Gold.  In early 2000, the band embarked on a U.S. promotional tour, and on the verge of the release of their album in the United States, the band was invited to tour with Britney Spears that summer in her U.S. Tour. They also made several appearances on Disney and Nickelodeon to promote their music. The band's debut became a hit in North America, where the album reached seventy-one on the Billboard 200 Albums Chart being certified Gold in September 2000, but its sales reached the million mark in 2001.  That month, the A-Teens won a Viva Music Award for Best International Newcomer, competing with the likes of Christina Aguilera and Blink-182, and also the band announced what would be the lead single from their second album and their first to be an original song, "Upside Down", which would also become their signature song. The song was released to Swedish radios on 23 October 2000, and was later unleashed worldwide. When the single was commercially released, it reached number two in Sweden and was later certified 2x Platinum. The song became the band's biggest hit when it reached the top ten in several countries and when the single was released in the United States. The physical single reached number six on the Billboard Hot 100 Single Sales Chart, selling over 500,000 copies in three weeks and being certified Gold. In January 2001, the band was nominated for "Best Swedish Group" at the NRJ Awards.
