Mariah put more thought into her craft than most girls, particularly Zzzline. Usually she failed but Moo had some cute moments. The other's moments were not cute. They were scientifically designed to be huge and last like 5 years then be embarrassing
Katy Perry's music will see a similar fate and Britney is already approaching Zzz territory. Maybe a little more nostalgic/less cringed at but also less listened to. If I remember correctly the only girl with worse recurrent play than her is Jennifer Lopez
