But her singles haven't done much in the long run this era. They have a strong few days and then drop hard. If anything, it proves that she has a fanbase but her sales are heavily front-loaded.
Not heavily in my opinion. Her songs usually stabilize within the Top 25-Top 50. She hasn't had a huge Top 10 smash in a long time though. It doesn't matter though, she's killing the competition regardless. 4 million album sales without a super smash?
