The issue being, it's kind of like the Megan The Stallion booking, she has 2 songs in the UK but she did have a full set of album songs. It's just nobody knew them here, save for a handful of super fans that know every word to every song. At the time we said she's got a year to bring out new material, but in the end she didn't.
It's a weird outright headline booking when the crowd only know Pink Pony Club, Hot to Go, Good Luck Babe, and the other 80 minutes are listening to tracks they don't really know.
Headliners really should be the act that can point a mic at the crowd for any song, and the whole crowd chants the lyrics in unison.
I hope she does bring out new hit material here, because she sounds a cross between Paramore and Charli XCX, but at this exact moment, both of those are more deserving of a top 3 spot.
