You're all about me now that you're my enemy
There's nothing here to save it's ALL in front of me
When I'm feeling low you're like a remedi!
I keep it to myself, I get the best of me!
Nothing new for Knee tho
Crazy and Oops I Did It Again and many of her Max Martin/bubblegum songs have other people sining the choruses
J Lo used to have other people singing her choruses back in the day as well
