Problem: Background: SMAP was a Japanese boy band, composed of Masahiro Nakai, Takuya Kimura, Goro Inagaki, Tsuyoshi Kusanagi, and Shingo Katori. The group was created in 1988 by music producer Johnny Kitagawa, founder of Johnny & Associates, originally as a six-piece with Katsuyuki Mori, until his departure from the band in 1996. After making their debut in 1991, the group took the Japanese entertainment industry by storm, becoming the most successful boy band in Japanese history and the bestselling band in Asia, often referred to as a "national treasure" and a "fortune and property of the country" in Japan. SMAP was regarded as an iconic figure in Japan, after achieving an unprecedented level of success in numerous genres in the entertainment industry, including music, television, film, radio, and theater, as a group and individually.
Context: SMAP was heavily involved in philanthropic activities. They have actively offered philanthropic support especially to the victims and regions affected by the 2011 Tohoku earthquake and tsunami and the 2016 Kumamoto earthquakes. On August 26 and 27, 1995, SMAP hosted NTV's annual telethon, 24 Hour Television, and raised 1.1 billion yen. On August 27 and 28, 2005, Kusanagi and Katori hosted the 24 Hour Television, again, and raised one billion yen.  In 2011, after the Tohoku earthquake and tsunami, they bought a 30-second television commercial block in their weekly television program, SMAPxSMAP, to air a commercial on the information about the Japanese Red Cross Society and a message from the band members encouraging people to donate. Rather than reusing the ones aired in the past, they have been reshooting the commercial every time they have a taping and have them aired every week at the end of the program. Since March 2011, they have actively worked as the members of Marching J, a charity organization established by their agency, Johnny & Associates. Each band member have also made individual donations.  On May 4, 2011, their first and only digital single, "Not Alone" was released. Initially scheduled to serve as the band's 46th single, it was later canceled and released digitally in light of the earthquake and the situation in Japan, considering circumstances in power shortages and distribution. One hundred yen per single downloaded was donated to the victims. On July 23 and 24, 2011, Nakai hosted the annual twenty-seven hour long television special, FNS 27 Hour Television, for the fifth time. A special episode of "Bistro SMAP", a cooking segment on SMAPxSMAP, was aired during the show, titled "Bistro SMAP On The Go". Four members flew to regions that were affected by the earthquake and tsunami, Kimura and Inagaki to Iwate prefecture and Kusanagi and Katori to Fukushima. The four members cooked a total of one-thousand meals to the victims evacuated in these areas. Nakai started to host his own music show, Ongaku no Hi, meaning "music day", to show their support to all those affected by the earthquake and tsunami. The program is aired every summer since 2011. On August 17, 2011, the band released their fifth compilation album, SMAP Aid, to support the people affect by the earthquake and tsunami. Two-hundred yen per album sold were donated to the victims. Being that it was the band's twentieth anniversary, many predicted a tour after the release of the album but the band canceled it due to power shortage in Japan that year.  After the 2016 Kumamoto earthquakes, the content of their 30-second long commercial changed, adding a new message by the band members toward the victims in Kumamoto. On April 24, ten days after the earthquake, Nakai made an unannounced surprise visit to an elementary school in Kumamoto, used as a shelter for the evacuees. He, later went back to Kumamoto on 2 more occasions: May 7  and again on May 15 with Katori.  On June 12, Kimura made a visit to Kumamoto as well.
Question: How much did they raise?
Answer: One hundred yen per single downloaded was donated to the victims.

Background: Expose is an American Latin freestyle vocal group. Primarily consisting of lead vocalists Jeanette Jurado, Ann Curless, and Gioia Bruno, the group achieved much of their success between 1984 and 1993, becoming the first group to have four top ten hits on the Billboard Hot 100 chart from its debut album, including the 1988 #1 hit "Seasons Change". In March 2015, Billboard magazine named the group the eighth most-successful girl group of all-time. The group was popular in dance clubs, mainstream Top 40 and adult contemporary charts in the United States.
Context: During the recording of the group's first studio album Exposure, the personnel of the group changed. Reports vary based on the source. According to People magazine, one of the original singers quit while two of the girls were fired midway through the recording of the first album, but according to Billboard, all three were fired. Arista records felt that the three original singers lacked star potential. Martinee states that he made the decision himself to replace the three girls, while Miller maintains it was all their choice, and Jurado confirms that Lorenzo wanted to leave. Shortly thereafter, Casanas pursued a solo career and Lorenzo pursued other ambitions; they were replaced by Jeanette Jurado and Gioia Bruno. Miller began a solo career; she was replaced by Ann Curless.  Lorenzo returned to the dance charts with the Vendetta Records releases "I Wanna Know" in 1988, and "Stop Me if I Fall in Love" in 1990, while Laurie Miller released the 12" single "Parallels" on Atlantic Records and a second single "Love is a Natural Magical Thing" on Meet Me In Miami Records. Laurie evolved into a headline performer frequently showcasing her talents on cruises with a more intimate jazz style, and formed her own entertainment company called Xica productions.  Casanas later resurfaced as a solo artist (Sandee) and released a solo album, Only Time Will Tell, which garnered the club hits "You're The One", "Love Desire", and the Clivilles & Cole-produced bassline-heavy hit "Notice Me". She continued to tour actively in dance clubs and freestyle shows, until her death on December 15, 2008, of a seizure at the age of 46. All three original members: Casanas, Lorenzo and Miller later contributed vocals on songs on the Miami group Will to Power's eponymous 1988 debut album. Gioia Bruno also provided lead vocals on Will to Power's 2004 album, Spirit Warrior.
