input: In 2002, Eminem heard Jackson's Guess Who's Back? CD, received from Jackson's attorney (who was working with Eminem's manager, Paul Rosenberg). Impressed, Eminem invited Jackson to fly to Los Angeles and introduced him to Dr. Dre. After signing a $1 million record deal, Jackson released No Mercy, No Fear. The mixtape featured one new track, "Wanksta", which appeared on Eminem's 8 Mile soundtrack. Jackson was also signed by Chris Lighty's Violator Management and Sha Money XL's Money Management Group.  Jackson released his debut album, Get Rich or Die Tryin' (described by AllMusic as "probably the most hyped debut album by a rap artist in about a decade"), in February 2003. Rolling Stone noted its "dark synth grooves, buzzy keyboards and a persistently funky bounce", with Jackson complementing the production in "an unflappable, laid-back flow". It debuted at number one on the Billboard 200, selling 872,000 copies in its first four days. The lead single, "In da Club" (noted by The Source for its "blaring horns, funky organs, guitar riffs and sparse hand claps"), set a Billboard record as the most listened-to song in radio history within a week.  Interscope gave Jackson his own label, G-Unit Records, in 2003. He signed Lloyd Banks, Tony Yayo and Young Buck as members of G-Unit, and The Game was later signed in a joint venture with Dr. Dre's Aftermath Entertainment. In March 2005 Jackson's second commercial album, The Massacre, sold 1.14 million copies in its first four days (the highest in an abbreviated sales cycle) and was number one on the Billboard 200 for six weeks. He was the first solo artist with three singles in the Billboard top five in the same week with "Candy Shop", "Disco Inferno" and "How We Do". According to Rolling Stone, "50's secret weapon is his singing voice - the deceptively amateur-sounding tenor croon that he deploys on almost every chorus".  After The Game's departure Jackson signed Olivia and rap veterans Mobb Deep to G-Unit Records, with Spider Loc, M.O.P., 40 Glocc and Young Hot Rod later joining the label, who all eventually departed the label. Jackson expressed an interest in working with rappers other than G-Unit, such as Lil' Scrappy of BME, LL Cool J of Def Jam, Mase of Bad Boy and Freeway of Roc-A-Fella, and recorded with several.

input: In late 1985, the band released their second album, Promise, which peaked at number one in both the UK and the US and became the band's first album to reach number one on the US Billboard 200. The album topped the chart in 1986 and spent two weeks at the peak position. Eventually, the album went on to sell four million copies in the region and was certified four times platinum by the Recording Industry Association of America (RIAA). The album spawned two singles "Never as Good as the First Time" and "The Sweetest Taboo," the latter of which was released as the album's lead single and stayed on the US Hot 100 for six months. "The Sweetest Taboo" peaked at number five on the US Billboard Hot 100, number one on the US adult Contemporary chart, and number three on the US Hot R&B/Hip-Hop Singles & Tracks. Sade was so popular that some radio stations reinstated the '70s practice of playing album tracks, adding "Is It a Crime" and "Tar Baby" to their playlists. The following year, 1986, the band won a Grammy Award for Best New Artist.  In 1986, Sade made her acting debut in Absolute Beginners, a film adapted from the Colin MacInnes book of the same name about life in late-1950s London. Sade played the role of Athene Duncannon and lent her vocals to the film's accompanying soundtrack. The film was screened out of competition at the 1986 Cannes Film Festival and grossed PS1.8 million in the UK. Sade's third album, Stronger Than Pride, was released on 3 May 1988, and like Sade's previous album became a commercial success and certified three times platinum in the US. The album was popularized by four singles, most notably the album's second single "Paradise", which peaked at number 16 on the US Billboard Hot 100 and peaked at number one on the US Billboard Hot R&B/Hip-Hop Songs, becoming the band's first single to do so.  Love Deluxe was released as the band's fourth studio album on 26 October 1992. The album peaked at number three on the US Billboard 200 and has sold 3.4 million copies in the United States. The album was later certified four times platinum by the RIAA for shipments of four million copies. The album was also commercially successful elsewhere, reaching number-one in France, and reaching the top ten in New Zealand, Sweden, Switzerland and the UK. The album went on to be certified gold in the United Kingdom. In November 1994, the group released their first compilation album, The Best of Sade. The album was another top ten hit in both the United Kingdom and the United States, certified platinum and four times platinum, respectively. The compilation album included material from Sade's previous albums, as well as a cover version of "Please Send Me Someone to Love" (1950), originally by Percy Mayfield.
