The fact that the Birthday lyric video is only 6 million views behind Roar's and it being one of the most watched lyric videos ever kinda makes the arguments that it's a bad song which no one was interested in completely moot. You don't generate that many viewers without being being interested in your song. It was clearly her try-hard video which sabotaged it.
She really needs a non-American in her close work circle. If I remember correctly it was mainly US viewers that found it funny after it premièred whilst WW people were like "What the hell?

" Humour changes drastically between countries and a non-American could've slapped some sense into her. (If there are non-Americans on her team then they're trash and need fired).
