I haven’t done the math, but on a per-album basis, is there a more successful female artist than Adele? She currently sits at #10 on the all-time sales list for women based on the performance of just three albums. Everybody above her has released at least twice as many.
Even more impressive is that she makes those numbers with seemingly very little effort. She just emerges every 4-5 years after being almost completely out of the spotlight, drops a new song, and watches it break every streaming record in the book.
