Document 9: Elton John (album): Elton John is the second studio album by English singer-songwriter Elton John, released on 10 April 1970 by DJM Records. It was released by Uni Records as John's debut album in the United States; many people there assumed it was his first album, as "Empty Sky" was not released in that country until 1975. "Elton John" includes his breakthrough single "Your Song", and helped to establish his career during what was considered the "singer-songwriter" era of popular music. In the US, it was certified gold in February 1971 by the Recording Industry Association of America (RIAA). In the same year, it was nominated for the Grammy Award for Album of the Year.
Document 10: List of songs recorded by Justin Timberlake: American singer-songwriter Justin Timberlake has written and recorded material for his four studio albums. Timberlake released his solo debut studio album, "Justified", in November 2002. Most of the record was produced by The Neptunes, with additional collaborators including Brian McKnight, Scott Storch, Timbaland, and The Underdogs. "Like I Love You", written by Timberlake, Chad Hugo and Pharrell Williams. "Cry Me a River", produced by Timbaland, is a R&B song about a brokenhearted man who moves on from his past. A "Rolling Stone" reviewer called the song a "breakup aria." Timberlake, Hugo and Williams also wrote "Rock Your Body" and "Señorita".
Document 11: Michael Jackson videography: American entertainer Michael Jackson (1958–2009) debuted on the professional music scene at age five as a member of The Jackson 5 and began a solo career in 1971 while still part of the group. Jackson has been called the King of Music Videos. Steve Huey of AllMusic observed how Jackson transformed the music video into an art form and a promotional tool through complex story lines, dance routines, special effects and famous cameo appearances, simultaneously breaking down racial barriers. Before "Thriller", Jackson struggled to receive coverage on MTV, allegedly because he was African American. Pressure from CBS Records persuaded MTV to start showing "Billie Jean" and later "Beat It", leading to a lengthy partnership with Jackson, also helping other black music artists gain recognition. MTV employees deny any racism in their coverage, or pressure to change their stance. MTV maintains that they played rock music, regardless of race. The popularity of his videos on MTV helped to put the relatively young channel "on the map"; MTV's focus shifted in favor of pop and R&B. His performance on "Motown 25: Yesterday, Today, Forever" changed the scope of live stage show; "That Jackson lip-synced 'Billie Jean' is, in itself, not extraordinary, but the fact that it did not change the impact of the performance is extraordinary; whether the performance was live or lip-synced made no difference to the audience" thus creating an era in which artists re-create the spectacle of music video imagery on stage. Short films like "Thriller" largely remained unique to Jackson, while the group dance sequence in "Beat It" has frequently been imitated. The choreography in "Thriller" has become a part of global pop culture, replicated everywhere from Indian films to prisons in the Philippines. The "Thriller" short film marked an increase in scale for music videos, and has been named the most successful music video ever by the "Guinness World Records".
Document 12: Cry Me a River (Justin Timberlake song): "Cry Me a River" is a song recorded by American singer and songwriter Justin Timberlake for his debut studio album, "Justified" (2002).

Jive Records released the song to contemporary hit and rhythmic radio in the United States on November 25, 2002, as the album's second single. Accompanied by an electric piano, beatbox, guitars, synthesizers, Arabian-inspired riffs and Gregorian chants, "Cry Me a River" is an R&B song about a brokenhearted man who moves on from his last girlfriend, who had cheated on him with another man.
