I find this video embarrassing. However, the demo version is so much better than the album version. It was toned down to mesh with the overall tone of BTD, which was a terrible mistake. She should fix up the demo and release it as a single on iTunes.
I just don't get why people want to make sense of the world. At the end of the day, we are all living on some random rock in the middle of a big black darkness which we know nothing about. It is pretty much a lost cause. Don't agonise over it...just enjoy life!
