Music recording certifications are typically awarded by the worldwide music industry based on the total units sold, streamed, or shipped to retailers. These awards and their requirements are defined by the various certifying bodies representing the music industry in various countries and territories worldwide. The standard certification awards given consist of Gold, Platinum, and sometimes Diamond awards, in ascending order; the UK also has a Silver certification, ranking below Gold. In most cases, a "Multi-Platinum" or "Multi-Diamond" award is given for multiples of the Platinum or Diamond requirements.
