The Neptunes Present...Clones is a compilation album produced and released by American production duo The Neptunes (producer-singer Pharrell Williams and producer Chad Hugo).
 It was released on August 19, 2003 and has been certified Gold by the RIAA.
 The album featured four singles; "Frontin'" by Pharrell Williams, "Light Your Ass on Fire" by Busta Rhymes, "Hot Damn" by Clipse and "It Blows My Mind" by Snoop Dogg.
"It Blows My Mind" is a song by American rapper Snoop Dogg, featuring guest vocals from American singer Pharrell Williams, taken from The Neptunes's first compilation album Clones.
 The song was written by Snoop Dogg, Chad Hugo and Pharrell, with production handled by The Neptunes.
"Like I Love You" is the debut single recorded by American singer Justin Timberlake for his debut studio album, "Justified" (2002).
 The song features American hip hop duo Clipse.
 It was co-written by Timberlake and The Neptunes (Chad Hugo and Pharrell Williams), who also produced it.
 The song was released on October 14, 2002 as Timberlake's debut solo single, following the break-up of 'NSYNC earlier that year.
 According to Williams, who came up with the music loop, the song's drums were an ode to the funk era.
Kenneth "Kenny O" Ortiz (born November 10) is an American record executive, songwriter, record producer, and is currently the CEO of World Trade Entertainment.
 Widely known as the driving force behind SWV, because he signed the group, picked their hits, got heavily involved in their creative process for original songs, remixes, mixes, collaborations, and last but not least established their vibe and brand.
 Ortiz is also known for discovering Pharrell Williams and Chad Hugo also known as the Neptunes, whom Ortiz signed to EMI to their first production and writing deal.
 Ortiz would A&R the unreleased compilation album which featured Charlie Wilson and Joe StoneStreet (the first member of Blackstreet) which subsequently led to Kelis's signing and recording.
 It was Kenny Ortiz's idea to make Pharrell and Chad to change their production name to the Neptunes (the name they went by as a group, which was later changed to N.E.R.D).
The Neptunes are an American production duo, composed of Pharrell Williams and Chad Hugo, who are credited with contributing the sound for many successful hip hop and R&B artists in the late-1990s and 2000s.
 The Neptunes' sound is a distinctive brand of off-kilter, stripped-down electronic funk with sounds from Middle Eastern and Asian music including percussion and woodwind.
 Pharrell sings and (later) raps on records and appears in videos, unlike his production partner Chad, who tends to stay behind the scenes.
In Search of... is the debut studio album by American funk rock band N.E.R.D.
 The group originally released the album on August 6, 2001 in Europe, where Kelis' "Wanderland"—produced by The Neptunes, consisting of N.E.R.D members Pharrell Williams and Chad Hugo—was better received.
 Similarly to Kelis' early work, the original version of "In Search of..." juxtaposes hip hop and rock influences and styles.
 The album is named after the TV series "In Search of...", hosted by Leonard Nimoy.
N*E*R*D (a backronym of No-one Ever Really Dies) is an American funk rock band.
 Pharrell Williams and Chad Hugo were signed by Teddy Riley to Virgin Records as a duo, The Neptunes.
 After producing songs for several artists throughout the late 1990s and early 2000s, the production duo formed the band with Shay Haley as a side project of The Neptunes in 1999.
 N*E*R*D's debut album, "In Search Of...", sold 603,000 copies in the United States and was certified Gold by the Recording Industry Association of America (RIAA).
 It was also awarded the second annual Shortlist Music Prize.
 The band's second album, "Fly or Die", sold 412,000 copies in the United States, but shipped at least 500,000 units, certifying it Gold.
