You also somehow forgot Lil Wayne has also released more albums since 2012, and will keep the lead once more with The Carter 5.
Except that total of his is from July 2013 and he has not released an album since unless you count his album with Young Money (which I doubt you will since you just tried DC).
Did you know Jay-Z did not go #1 with an album in a country that wasn't US until 2009?
It took him 13 years, and 13 albums. The country was Canada ofcourse! He didn't go #1 in a country outside North America until this decade, thanks to Kanye West.
so being local is a (familial) genetic trait. poor Rapunzel
