Ricki-Lee said she wanted 'Crazy' to be "sensual and erotic".
"I wrote it as if I was singing directly to the people on the dance floor … encouraging you let go of your inhibitions, go crazy and let the music take over."
Speaking of sensual, Ricki-Lee has embraced her inner futuristic Amazon on the cover of her upcoming album Fear & Freedom.
"The album is about unleashing your inner strength, rising above all the thing that ever held you back and being free to do whatever you want to do in life," she said.
"So the cover has that really epic, empowered and almost superhero-esque feeling about it and I'm so in love with it!"
