Selling a million album is something, no matter if we talk about pure album sales or converted singles formats. It takes a lot of success to get there. Climbing all the way to 10 million is all the more difficult while hitting 100 million is some kind of a legendary achievement. The last artist to do so? Britney Spears who debuted way back in 1998. Thanks to strong ongoing sales, several 00s artists are now on their way to get there too. Rihanna, Coldplay, Adele, Taylor Swift, Beyoncé, they are all contenders to reach 9 digits sales. Who will do it first though? Also, can younger artists like Ed Sheeran, Justin Bieber, and Drake be dark horses and top them all?
