What's the point in comparing her to a legend? X's 1st album sold more than Selena will ever sell now, and until she retires. None of her group albums sold more than Bionic for God's sake.
Wallonia and Flanders are both "official", we have two charts here.
I know they are both official but I said Flanders was the main chart since it's the one referenced in press releases and on sites with chart stats such as the one I posted.
