I still love it and think it's so underrated I love how it's an empowering, anthemic song, but it's also different from anything she's put out before. It sounds so grandiose, especially the last chorus after her big note...those drums are huge and Sia's background vocals, it sounds epic
I really like Invincible. It shouldn't flopped. I love the big note towards the end, and then how Kelly uses her higher register - beautiful! It really showcases a part of her voice that hasn't used a whole lot in the past.
Also, off topic but Take You High needs to be a single.
