In the United States, the Recording Industry Association of America awards certification based on the number of albums and singles sold through retail and other ancillary markets. Other countries have similar awards (see music recording sales certification). Certification is not automatic; for an award to be made, the record label must request certification and pay a fee to have the sales of the recording audited. The audit is conducted against net shipments after returns (most often an artist's royalty statement is used), which includes albums sold directly to retailers and one-stops, direct-to-consumer sales (music clubs and mail order) and other outlets..

Presently, an American RIAA-certified Gold record is a single or album that has sold 500,000 units (records, tapes or compact discs). Originally, the requirement for a Gold single was one million units sold and a Gold album represented $1 million in sales (at wholesale value). In 1975, the additional requirement of 500,000 units sold was added for Gold albums. Reflecting growth in record sales, the Platinum award was instituted in 1976 for albums selling one million units and singles selling two million units. The Multi-Platinum award was instituted in 1984, signifying multiple Platinum levels of albums and singles. In 1989, the sales thresholds for singles were reduced to 500,000 for Gold and 1,000,000 for Platinum, reflecting a decrease in sales of singles. In 1992, RIAA began counting each disc in a multi-disc set as one unit toward certification. Reflecting additional growth in music sales, the Diamond award was instituted in 1999 for albums or singles selling ten million units. Because of these changes in criteria, the sales level associated with a particular award depends on when the award was made.

Amanda Leigh "Mandy" Moore (born April 10, 1984) is an American singer-songwriter, actress and fashion designer. Moore became famous as a teenager in the late 1990s, after the release of her teen pop albums So Real, I Wanna Be with You, and Mandy Moore. In 2007, she took an adult pop-folk direction with the release of Wild Hope. Her most recent album, Amanda Leigh, was released on May 26, 2009. Moore has sold more than 10 million records worldwide. Moore subsequently branched out into film, starring in 2002's A Walk to Remember and later in other movies, such as Chasing Liberty, Saved! and License to Wed. Most recently Moore provided the voice of Rapunzel in Tangled. In April 2011, she ranked 5th in People's annual Most Beautiful issue.

Moore was born in Nashua, New Hampshire. Her mother, Stacy (née Friedman), is a former news reporter who once worked for the Orlando Sentinel, and her father, Donald "Don" Moore, is a pilot for American Airlines. Moore's father is of Irish and Cherokee descent, and her mother is of half-English and half-Jewish ancestry. Moore, who has an older brother Scott and a younger brother Kyle, grew up in Longwood, Florida, outside of Orlando, where the family moved shortly after her birth because of her father's job as an airline pilot. She was raised Catholic (though she is no longer practicing), and attended Bishop Moore High School, in Orlando, as well as Lake Brantley High School in Altamonte Springs.

Eric Lynn Wright (September 7, 1963 – March 26, 1995), better known by his stage name Eazy-E, was an American rapper who performed solo and in the hip hop group N.W.A. Wright was born to Richard and Kathie Wright in Compton, California. After dropping out of high school in the tenth grade, he supported himself primarily by selling drugs before investing in Ruthless Records and becoming a rapper. When Ruthless artists Dr. Dre and Ice Cube wrote "Boyz-n-the-Hood", Dre, Cube, and Eazy formed N.W.A. After DJ Yella, MC Ren, and Arabian Prince joined the group, N.W.A released N.W.A. and the Posse. In 1988, they released their most controversial album, Straight Outta Compton. The group released two more albums and then disbanded after Eazy released Dr. Dre from his contract.

Eazy's main influences included 1970s funk groups, contemporary rappers, and comedians. When reviewing Eazy's albums, many critics noted his unique overall style, with Steve Huey of the All Music Guide summing up: "While his technical skills as a rapper were never the greatest, his distinctive delivery (invariably described as a high-pitched whine), over-the-top lyrics, and undeniable charisma made him a star." On February 24, 1995, Eazy was admitted into Cedars Sinai Medical Center in Los Angeles with what he believed to be asthma, but was instead diagnosed with AIDS. On March 16 he acknowledged his condition publicly, and died due to complications ten days later.

Alan Parsons (born 20 December 1948) is a British audio engineer, musician, and record producer. He was involved with the production of several significant albums, including The Beatles' Abbey Road and Let It Be, as well as Pink Floyd's The Dark Side of the Moon for which Pink Floyd credit him as an important contributor. Parsons' own group, The Alan Parsons Project, as well as his subsequent solo recordings, have also been successful commercially.

In October 1967, at age 18, Parsons went to work as an assistant engineer at Abbey Road Studios, where he earned his first credit on the LP Abbey Road. He became a regular there, engineering such projects as Paul McCartney's Wild Life and Red Rose Speedway, five albums by The Hollies, and Pink Floyd’s The Dark Side of the Moon, for which he received his first Grammy Award nomination. He was known for doing more than what would normally be considered the scope of a recording engineer’s duties.^{[citation needed]}He considered himself to be a recording director, likening his contribution to recordings to what Stanley Kubrick contributed to film.^{[citation needed]} This is apparent in his work with Al Stewart's "Year of the Cat", where Parsons added the saxophone part and transformed the original folk concept into the jazz-influenced ballad that put Al Stewart onto the charts.^{[citation needed]} It is also heard in Parsons' influence on the Hollies' "He Ain't Heavy, He's My Brother" and "The Air That I Breathe", sharp departures from their popular 1960s hits "Stay", "Just One Look", "Stop! Stop! Stop!" or "Bus Stop".^{[citation needed]} Parsons was also known to have swapped shifts during the engineering of The Dark Side of the Moon so he could work entirely on the project.^{[citation needed]}
