This is interesting.
I don't know if its positive or negative the fact that she improved in her singles performances but declined in album sales between "Bionic" and "Lotus" in US.
Bionic's 2 singles flopped and bombed terribly in the US specially "You lost me
", while both Lotus' singles achieved -Gold- status in the US (one of them with no performances and a peak outside top 30, and the other one without a music video), a Gold single is nothing to be impressed these days though, but at least an imporvement in the singles department.
In terms of albums sales it was the opposite, "Lotus
" sales were disappointing considering the album was released by the end of the year and had Black friday and Christmas sales unlike "Bionic
Despite the singles improvement in the US , the situation is not the same worldwide, I still think "Not myselft tonight
" remains as her best chart performer (solo) single worldwide since 2010.
