"WANNA BE INSIDE OF YOU!"
I've said this before. If you sing the pre-chorus "I live for the applause... etc." over the original instrumental by DJWS when the part "Give me the thing that I love! - Turn the lights out! etc." begins, it becomes an even better song. Replace the spelling part with "Way that you cheer and scream for me... etc.", it becomes instantly catchy and Poker Face-level uplifting.
They should've kept the breakdown and the K-Pop/J-Pop sounding effects in it as well. Even as an electropop song, it could've sound fresh last year with the obvious outlandish vibe they were going for. This song had so much ****ing potential. It would've been her 4th number 1 and a worldwide hit, I'm sure of it.
