Britney or Beyoncé, the UK doesn't really care for either of them anymore. 4 sold more than self titled while her highest charting song since 2011 peaked at #9, while Work Bitch peaked at #7 before falling to #37 the next week, and Pretty Girls peaked at #16 before falling to #55.
Britney yes, Beyoncé no. Her recurrent airplay slays
Also self-titled had a really good chart run and peaked in its like 5th week I believe.
