From the primitive (organizationally speaking) and inaccurate charts of the ‘30s and ‘40s to the modern era of YouTube and digital sales, the criteria of commercial success have changed so drastically that we can’t realistically compare the artists of today with yesterday. For example, back in the ‘90s an album’s price started at $25 and could reach $40 or more (for a double album), while nowadays for ninety-nine cents you can download Taylor Swift’s and Rihanna’s new songs on your phone, which in theory counts as buying a record that cost twenty and thirty times as much in the ‘80s and ‘90s. For this reason the Recording Industry Association of America (RIAA) recently divided the all-time charts between physical record sales and digital sales. Even though we intentionally excluded modern artists from our list for the aforementioned reason, we also left out music giants such as Bing Crosby, Frank Sinatra, ABBA, Bee Gees, Diana Ross, and Deep Purple among others, simply because we don’t have enough official figures for their actual sales, but only claims. After taking into account every official source we could find in the music industry we proudly present the most accurate (in terms of total certified units sold from official markets) chart of the 25 top selling music artists of all time. Nonetheless, Dion undoubtedly remains one of the best-selling female artists of all time with certified sales of over 125 million copies while her record company makes claims of over 200 million albums sold worldwide. Despite all the records they have broken and being the most famous music band of the twentieth-century, their claims of 1.5 billion records worldwide has proved to be false even though it seems very possible for them to become the first music act to soon break the 300 million barrier of certified sales if their albums continue to sell as well as they have for the past two decades.
