David Styles (born November 28, 1974), better known by his stage name, Styles P, is an American rapper, author, and entrepreneur.
 He is prominently known as a member of Hip Hop group The Lox, founder of D-Block Records and is also a part of the Ruff Ryders hip-hop group, and in addition has released multiple albums and mixtapes as a solo MC.
 In 2002, he released his debut album "A Gangster and a Gentleman".
 He went on to release "Time is Money" (2006), "Super Gangster (Extraordinary Gentleman)" (2007), "Master of Ceremonies" (2011), "The World's Most Hardest MC Project" (2012), "Float" (2013), "Phantom and the Ghost" (2014), and "A Wise Guy and a Wise Guy" (2015).
Mel Jason Smalls (born January 4, 1980), better known by his stage name Drag-On, is an American hip hop recording artist and actor from the Bronx borough of New York City.
 Drag-On is perhaps best known as an original member of the Ruff Ryders Entertainment imprint, where he released his debut album, "Opposite of H2O" (2000).
 The album was successful, debuting at number five on the US "Billboard" 200 chart and eventually sold over 500,000 copies and earning a gold certification from the Recording Industry Association of America (RIAA).
 After leaving Interscope Records, which issued his debut alongside Ruff Ryders, Drag-On joined Virgin Records and released his second album "Hell and Back", in 2004.
 Hell and Back did not sell like Opposite of H2O.
 However, it did very well for an album that did not receive any promotions, radio spins, or advertising.
Let There Be Eve…Ruff Ryders' First Lady is the debut album of American rapper Eve.
 The album was released September 14, 1999 on Ruff Ryders Entertainment and Interscope Records.

 The album has sold over 2 million copies (according to Soundscan) and is certified Double Platinum.
 The album features singles such as "Gotta Man," and "Love Is Blind" with Faith Evans.
 All of the songs on the album were written by Eve herself.
 Eve became the third female hip-hop artist to have her album peak at number one on the "Billboard" 200 (Lauryn Hill's debut album, "The Miseducation of Lauryn Hill", being the first to top the chart in 1998 and Foxy Brown's second album, "Chyna Doll" achieving the feat earlier in 1999).
The Great Depression is the fourth studio album by American rapper DMX.
 The album was released October 23, 2001, by Ruff Ryders Entertainment and Def Jam Recordings.

"Smoke" is a song by American hip hop recording artist 50 Cent, released on March 31, 2014, as the fourth single from his fifth studio album "Animal Ambition" (2014).

"Hustler's Ambition" is a song by American rapper 50 Cent.
 Written by 50 Cent and produced by B-Money "B$", the song was released as the first single from the soundtrack to the film "Get Rich or Die Tryin' " (2005).
 Built around a soul–influenced production sampling the Frankie Beverly and Maze song "I Need You", "Hustler's Ambition" features lyrics regarding 50 Cent's rise to fortune and fame, intended to mirror the experience faced by 50 Cent's character in the film: it marks a shift from influence of hardcore hip hop present in 50 Cent's earlier work.
 "Hustler's Ambition" was released to digital retailers in the United States in October 2005 via Interscope Records, with a CD release following in February 2006.
