input: At age eleven, BoA accompanied her older brother to an SM Entertainment talent search. Though her brother was the one who auditioned as a break-dancer, SM talent scouts instead took notice of BoA and offered her a contract on the same night as the auditions. Her parents initially opposed the notion of BoA's leaving school to enter the entertainment business but eventually consented at her older brothers' persuasion. She has said that her early influence as a singer was Seo Taiji.  BoA underwent two years of training (involving vocal, dance, English, and Japanese lessons), and at the age of thirteen released her debut album ID; Peace B in South Korea on August 25, 2000. The album was moderately successful; it entered the Top 10 of the South Korean charts and sold around 156,000 units. Meanwhile, her Korean record label, SM Entertainment, made arrangements with Japanese label Avex Trax to launch her music career in Japan. She was forced to quit school to prepare and in early 2001, BoA released her first mini-album, Don't Start Now; it sold around 90,000 units. After its release, she took a hiatus from the Korean music industry to focus on the Japanese market at which time she worked to solidify her skills in Japanese.  BoA began her Japanese music career singing at the Avex-owned club Velfarre. In 2001, she released her debut Japanese single, a Japanese version of the song, "ID; Peace B" (originally from the eponymous album). The single reached No. 20 on the Oricon chart and was followed by "Amazing Kiss", "Kimochi wa Tsutawaru", and "Listen to My Heart"; the last became the singer's first single to enter the Oricon's Top Five. After the September 11, 2001 attacks, BoA recorded the charity single "The Meaning of Peace" with Kumi Koda as part of Avex's Song Nation project to raise funds for charity. From 2001 to 2007, BoA hosted Beat it BoA's World, a radio program on the Japan FM Network.  Her debut Japanese album, Listen to My Heart, was released on March 13, 2002. The album was a breakthrough in BoA's career: it became an RIAJ-certified million-seller and debuted atop the Oricon, the first album by a Korean artist to do so. A single, "Every Heart: Minna no Kimochi", was released on the same day as the album. After the release of Listen to My Heart, BoA released her second Korean studio album, No. 1, a month later. The album sold around 544,000 units and became the fourth-best-selling record of the year in South Korea. Jumping into the World (a Japanese re-release of the mini-album Don't Start Now) and the Japanese single "Don't Start Now" were released a month later on the same day.  BoA then released her seventh single "Valenti". It peaked at the number-two position on the Oricon chart. BoA released two more singles "Kiseki / No.1" and "Jewel Song / Beside You: Boku o Yobu Koe", both which also peaked at the number-three position. At the end of the year, BoA released her second Korean mini-album Miracle.

input: Before Hammer's successful music career (with his mainstream popularity lasting approximately between 1988 and 1998) and his "rags-to-riches-to-rags-and-back saga", Burrell formed a Christian rap music group with CCM's Jon Gibson (or "J.G.") called Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as K.B. and then eventually M.C. Hammer once it was produced), was later released on Gibson's album Change of Heart (1988). This was Contemporary Christian music's first rap hit ever. Burrell also produced "Son of the King" at that time, releasing it on his debut album. "Son of the King" showed up on Hammer's debut album Feel My Power (1987), as well as the re-released version Let's Get It Started (1988).  With exception to later remixes of early releases, Hammer produced and recorded many rap songs that were never made public, yet are now available on the Internet. Via his record labels such as Bust It Records, Oaktown Records and FullBlast, Hammer has introduced, signed and produced new talent including Oaktown's 3.5.7, Ho Frat Hoo!, the vocal quintet Special Generation, Analise, James Greer, One Cause One Effect, B Angie B, The Stooge Playaz, DASIT (as seen on ego trip's The (White) Rapper Show), Teabag, Common Unity, Geeman and Pleasure Ellis; both collaborating with him and producing music of their own during his career.  At about the age of 12, Oakland native Keyshia Cole recorded with Hammer and sought career advice from him.
