I'm so certain this samples Daniel Bedingfield's Gotta Get Thru This.
It was bugging me what song this made me think of. The beat also reminds me of a cross of 2 Chainz "I'm Different" (the piano key) and Kid Ink's "Body Language"
Either way this is probably my FAVE fifth harmony track in their discography.
The song already does very well, aslong as their label realises that and plays on that and won't wait weeks (for additional promo), if this actually actually could go top 15 or higher.
I so thought Camila's dance was awkward at first because I thought she almost fell lmfao. I wish Dinah and Camila bounced back and forth singing "we can work from home" at the end of the song.
Theory
I think that the chorus is lead by Lauren with Camila and Ally's vocals in the back. During the chorus scenes, they are the only ones mouthing the words. But it's like that for every chorus scene in the video.
