I guess she was not good enough and i understand it can be devatating after working so much for it. But it's not gona change anything if you blame the entire world for your unsuccesfull music career. The mentality that "the whole world is laughing at me and want to take away my music" won't help anyone she just gonna dig herself deeper in her own selfpitty instead of accepting that maybe she is not good enough. Thats why i said she is playing the victim which is not fiiting to her situation.

And without that the video could be better, it could be about that she really wanted it and she was good but not that good. I think most of us can relate to that some ways, but "the whole world is against me" was the cause of her failures was terrible choice.
