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.

King Arthur is a legendary British leader of the late 5th and early 6th centuries, who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the early 6th century. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources, including the Annales Cambriae, the Historia Brittonum, and the writings of Gildas. Arthur's name also occurs in early poetic sources such as Y Gododdin.

The legendary Arthur developed as a figure of international interest largely through the popularity of Geoffrey of Monmouth's fanciful and imaginative 12th-century Historia Regum Britanniae (History of the Kings of Britain). Some Welsh and Breton tales and poems relating the story of Arthur date from earlier than this work; in these works, Arthur appears either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, sometimes associated with the Welsh Otherworld, Annwn. How much of Geoffrey's Historia (completed in 1138) was adapted from such earlier sources, rather than invented by Geoffrey himself, is unknown.

Brett Domino is the alter-ego of Youtube musician Rob J. Madin. As Brett Domino, he is a musician, internet celebrity and TV presenter from Leeds, West Yorkshire, England. He is best known for his YouTube videos, in which he plays mostly covers and medleys of popular songs on the Stylophone and keytar - sometimes with his band, 'The Brett Domino Trio'. The band is notable in that its members (Brett Domino, Steven Peavis (Ste Anderson) and Mitch Hutchinson (Michael Denny)) all play exclusively keyboard instruments. In a number of recent videos, however, Brett and Steven have diversified to incorporate other instruments, such as ukulele, theremin, recorder, accordion, kalimba and Skoog. Brett and the band have been featured a number of times as part of BBC Radio 1's Chris Moyles Show, and in 2009 the band appeared on ITV's Britain's Got Talent, performing live as the house band on two episodes of ITV2's sister show, Britain's Got More Talent, in the final week.

Brett's Youtube videos have received over 11,000,000 views. The Justin Timberlake Medley featuring Trabasacks was posted by Justin Timberlake on his Twitter page and official website.

Salvatore Ferragamo (June 5, 1898 – August 7, 1960) was an Italian shoe designer. He worked with many Hollywood stars in the 1920s, before returning to Italy to found the eponymous company making unique hand-made footwear. His scientific and creative approach to shoes spawned many innovations such as the wedge heel and cage heel. Film stars and celebrities continue to patronize his company, which has evolved into a luxury goods empire spanning the world.

Salvatore Ferragamo was born in 1898 in Bonito, near Avellino, the eleventh of 14 children. After making his first pair of shoes at age nine, for his sisters to wear at their confirmation, young Salvatore decided that he had found his calling. He always had a passion for shoes. After studying shoemaking in Naples for a year, Ferragamo opened a small store based in his parent's home. In 1914, he emigrated to Boston, where one of his brothers worked in a cowboy boot factory.

After a brief stint at the factory, Ferragamo convinced his brothers to move to California, first Santa Barbara then Hollywood. It was here that Ferragamo found success, initially opening a shop for repair and made-to-measure shoes, which soon became prized items among celebrities of the day, leading to a long period of designing footwear for the cinema. However, his thriving reputation as 'Shoemaker to the Stars' only partially satisfied him. He could not fathom why his shoes pleased the eye yet hurt the foot, so he proceeded to study anatomy at the University of Southern California.
