Starting from the 1990s to the 2010s (so far), I tried to put together a list of the Top 10 biggest female album acts of each decade. I'll be adding the 1980s if there's enough demand (though sales from back then are harder to find/estimate which is why I'm not including them as of right now). If you notice any mistakes please let me know!
