I dunno, Dua’s had a load of number 1 hits. She’s a big pop star. SZA, same - loads of Grammy awards, and both have lots of critical acclaim as well.
Simz and PJ Harvey are both mercury award winners (PJ twice). Janelle Monae is amazing and gets great reviews for everything she does
They’re all there on merit!
I don’t really know what you expect from the festival organisers, it sounds like they had to get the third headliner in last minute too. What other blokes would be better bookings than the women above?
