I purposely left him out. He has the bestselling album of 2013 and he has sold 3 million albums this year (not including his fantastic catalog sales,) 15 years into his career.
Wait... Katy the "singles artists" is outselling Gaga the "queen of pop" in album sales, even though the album came out almost a whole month before? Welp, slay the competition.
Good numbers for Brit! Hopefully she can get that #2 debut!
