Where exactly is Sia on that bonus track? I only hear her a little near the end but that is it haha! On first listen most tracks sound a bit generic and kind of samey. I like it for the most part though, it is similar to the stuff they did of Answer and its a cohesive album but maybe its just a bit too safe - there is too little rap and more pop. Of course I haven't found the time to read the translation of the lyrics, I am sure they still pushing their positive messages across.
