From the band found here:

“’CHA-CHING’ is about owning your own ‘awesome’. We’re living in a world ruled by social media and our own doubts and comparisons from those platforms,” the band explains. “We wanted to write a song about feeling empowered to be ourselves.

“A song about ‘feeling like a million bucks’ in our skin as we are today; a bit messy, less than ‘perfect’ but f***ing cool because we’re proud to be our own unique weird!”
