List of best-selling music artists

Gold/Platinum certifications issued after 2016, especially on singles, are in some cases more than 50% streaming generated. Some of the 20th century artists can also have significant amount of streaming based certifications. The certified units of the newer artists may sometimes be higher than their listed claimed figures. This is because Recording Industry Association of America (RIAA) and almost all other certifying bodies count streaming towards Gold and Platinum thresholds required for Digital Single Award certification.[1][2][3] For this reason, some singles and even albums get over certified by hundreds of thousands of units. The over certified figures, however, are often in millions of units for RIAA certifications, one such example is Rihanna's single "We Found Love", which is certified at nine times Platinum by the RIAA, yet during the time of the certification, it had sold 5.4 million downloads.[4][5]

The certified units for some artists/bands who have multi-disc albums can be higher than their listed claimed figures due to the RIAA counting each unit within set as one unit toward certification. The certified units also can be inflated by the redundancy of certifications, because each of tracks downloads and streams contributed to the certifications of both of the single and the respective album. The RIAA counts 10 downloads of individual track as well as 1,500 audio/video streams as an equivalent to one unit of album, including those from singles released prior to the album release.[6] Theoretically, if one song were streamed 1.5 billion times on YouTube, the single would receive Diamond and the whole album could be certified Platinum,[7] thus creating a combined total of 11 million certified units without any sales. Kanye West's album The Life of Pablo achieved Platinum without selling a single copy and was only available for streaming.[8]

Issued certifications for songs which have been recorded by multiple artists including featured artists are added to each artist's total amount of certified units, as all the artists would have played a significant part in a song. For example, "This Is What You Came For" and "Where Them Girls At" include Rihanna and Flo Rida, Nicki Minaj as featured artists respectively, so the certifications issued for these songs are added to the total amount of certified units for all involved artists. However, the certifications issued for songs that have been recorded by four or more artists are not included as the artists involved would have played minor roles, examples of such songs are Kanye West's "Monster" and/or "All Day".[lower-alpha 1]
