Music recording sales certification is a system of certifying that a music recording has shipped or sold a certain number of copies, where the threshold quantity varies by type (such as: album, single, music video) and by nation or territory (See also: List of music recording certifications).

Almost all countries follow variations of the RIAA certification categories, which are named after precious materials. The thresholds below are used in the United States and United Kingdom only. For other countries definitions, see List of music recording certifications:

The number of sales or shipments required for these awards depends upon the population of the territory in which the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country in which the album is sold. Different sales levels, some perhaps 10 times lower than others, may exist for different music media (for example: videos versus albums, singles, or downloads).

Originally applied to LP records, certification is now most commonly awarded for compact disc (CD) sales.^{[citation needed]} Certification is often awarded cumulatively, and it is possible for a single album to be certified silver, gold, and platinum in turn. An album that becomes platinum twice over is said to be "double-platinum"; three-times over, "triple-platinum", etc., which can all be generalized with the term "multi-platinum". Artists can also become multi-platinum sellers if they have at least two albums in the same territory both going single Platinum. A poor-selling record is often jokingly said to have "sold lead" (the heavy metal lead), in contrast to attaining high status as a gold or platinum album.

Mick Guzauski (also "Mic Guzauski," and "Mick 'Mix Maestro' Guzauski") is a multi-platinum Mixing Engineer and sound engineer.

Guzauski's work spans a wide range of styles, including jazz, R&B, Latin, rock, pop, and easy listening. He won a 2002 Latin Grammy for Thalía's "Arrasando", four 2004 Latin Grammys for Alejandro Sanz's "No Es Lo Mismo" (including Best Engineered Album), and the 2006 Grammy Award for Best Engineered Album, Non-Classical, for Eric Clapton's "Back Home." As of 2001, he had mixed 27 # 1 singles.

Guzauski grew up in Rochester, New York, where there were no commercial sound studios. In high school he put together his own studio in his parents' basement with equipment that he borrowed, built, repaired, and modified. He did pickup engineer work with Steve Gadd and Tony Levin, then students at the Eastman School of Music, and Lou Gramm, who soon hit it big with Foreigner.

Around the same time, he met Chuck Mangione, an up-and-coming composer in Rochester, and engineered his recordings as well as mixed his live sound. When Mangione signed with A&M Records in 1975, he asked Guzauski to go to Los Angeles with him to engineer his new album, a recording with a 45-piece orchestra with a rhythm section and soloists at A&M studios. Guzauski engineered several albums for Mangione over the next few years.
